Icing significantly reduces the electrical performance of insulators, and grid failures caused by insulator icing are common. Currently, most research on the flashover characteristics of insulators under icing conditions focuses on artificially iced suspension insulators, with limited studies on post insulators under natural icing conditions. The shed spacing of post insulators is smaller, making them more prone to bridging by icicles in the same icing environment, which exacerbates insulation problems. Therefore, investigating the icing characteristics of post insulators is crucial. In this study, natural icing growth was observed on seven different types of post insulators at the Xuefeng Mountain Energy Equipment Safety National Observation and Research Station. The icing morphology and characteristics of these insulators were examined. The main conclusions are as follows: (1) the icing type and morphology of post insulators are influenced by meteorological conditions, with more severe icing observed on the windward side. (2) The icing mass and icicle length of the insulator increase nonlinearly with icing time. Specifically, during the glaze icing period from 0 to 8 h, the ice mass on the Type V composite post insulator was 3.89 times greater than that during the 13-to-18 h period. (3) Within the same icing cycle, the icing growth rate on composite post insulators is faster than on porcelain post insulators. (4) Compared to suspension insulators, the sheds of post insulators are more easily bridged by icicles. Notably, when the sheds of post insulators are bridged by icicles, the length of icicles on suspension insulators is only half of the gap size. [ABSTRACT FROM AUTHOR]

A bone china grouting slurry was prepared using two different milling methods: low-energy ball milling (Named LBC) for 24 h and high-energy ball milling (Named HBC) for 1 h. Bone china green bodies were formed by grouting, and the dried green bodies were calcined at different temperatures points in the temperature range from 1235 °C to 1255 °C. The slurry characteristics, as well as the structure and properties of the calcined samples, were analyzed and evaluated. The particle sizes of LBC and HBC slurry D50 are 5.819 μm and 3.571 μm, respectively, accounting for 80.4 % and 98.7 % of their respective proportions. The particle size distribution range of HBC samples was relatively concentrated, and the viscosity of the two slurries was 1040 mPa s and 2800 mPa s, respectively. The ball milling method significantly influenced the formation of product phases. The content of calcium feldspar and β-TCP phases in HBC samples calcined at 1245 °C was higher than that in their LBC counterparts, while the quartz content in LBC was higher than that in HBC samples. The water absorption and porosity of the HBC samples were lower than those of the LBC samples, with a flexural strength of 205 MPa, heat shock temperature difference of 190 °C, and light transmittance of 5.18 %/3.73 mm, which were 22.4 %, 26.7 %, and 4.2 % higher than those of the LBC samples, respectively. These results indicate that bone china prepared using the high-energy ball milling method exhibits excellent performance. [Display omitted] [ABSTRACT FROM AUTHOR]

In 2020, the complete Xixia porcelain kiln site at Suyukou was excavated. A large number of fine white porcelain products and various kiln furniture items were unearthed. Surrounding the kiln site, mining pits for raw materials and fuels, such as porcelain clay, coal, quartz, and limestone, were discovered. The kilns are designed as horseshoe-shapedt cross-draft mantou kilns, traditional in northern China. These newly discovered kilns can be referred to as Helan kilns. For the first time, remains necessary for a full technological sequence of porcelain-making were discovered. Additionally, the porcelain firing site used by the Xixia imperial house was also found. The highly advanced firing technology at this kiln site is unprecedented in previously excavated archaeological sites. [ABSTRACT FROM AUTHOR]

Black and white porcelain plays a critical role in Chinese decorative porcelain history. It is famous for its decorative styles and techniques, which create a strong black and white color contrast in its appearance. In this study, representative black and white porcelains produced in Shanxi province were analyzed by X‐ray fluorescence, Raman spectroscopy, and SEM‐EDS. The results show that both Ca‐rich (~5.33 wt%) and Ca‐poor (~1.99 wt%) glazes were used leading to quite different microstructures. The pigment particles of Ca‐rich glazes are characterized by small size (≤2 μm), wide distribution, and tightly wrapped by anorthite. In contrast, they are larger (≥2 μm) and tightly cumulated together in Ca‐poor glazes. Hematite is the major crystal in pigment, double‐substituted by Al and Ti. The Al/Fe ratios are similar, but Ti/Fe ratios are quite different: They do not exceed 0.03% in Ca‐poor glazes, whereas they reach 0.12% in Ca‐rich glazes, suggesting that the origin of the pigments must be different. Al‐rich mineral such as kaolin was added to the pigment preparation in Ca‐rich glazes. The color of the pattern is mainly influenced by the size, quantity, and concentration of brown Ti‐doping hematite, as well as the thickness of the glaze layer and other crystals and Fe ions. The fired atmosphere of Ca‐rich glaze type seems less oxidizing than for Ca‐poor glaze type. Overall, the results confirm that black and white porcelain has a variety of production techniques, which is attributed to the craftsman adjusting the techniques according to the composition of raw materials.

We present portable X‐ray fluorescence data on the composition of body, glaze and enamels of several Meissen porcelain objects associated with the Hoym–Lemaire Affair (1728–1731). In 1728, the French merchant Rodolphe Lemaire convinced the Meissen Porcelain Manufactory into making copies of Japanese Kakiemon porcelain for sale as originals in Paris, a dubious enterprise that depended on the development of additional pigments closely emulating the Kakiemon palette. We shall illustrate how the color formulations for these objects, designed to imitate Japanese porcelain, differ from those on earlier porcelain from 1723–24, as well as later (mid‐18th century) objects. In all cases, the colorant chemistry can be related to special recipes introduced by Johann Gregorius Höroldt specifically for this purpose and preserved in the Meissen archives. A surprising observation is the absence of antimony or tin in the yellow colorant. As an ancillary finding, we have confirmed analytically for the first time that unmarked, undecorated Meissen porcelain in storage since prior to 1725 was decorated around 1730 and became part of the Hoym–Lemaire shipment.

The rise of porcelain industry in northern China and the subsequent emergence of white porcelain production during the Northern dynasties (386–581 CE) played a pivotal role in shaping the historical trajectory of Chinese ceramics. Xing kiln is one of China's earliest and most representative white porcelain kilns. Herein, we investigated 23 porcelain sherds from the Neiqiu Xing kiln site during the late Northern dynasties and the early Sui dynasty (550–600 CE) from the perspective of firing temperature, firing atmosphere, and microstructure using a dilatometer, X‐ray photoelectron spectroscopy, and scanning electron microscopy. The results show that the early Xing porcelains were fired at high firing temperatures exceeding 1200°C with a reducing flame, and the adjustment of temperature promotes the emergence of early white porcelain. Moreover, the higher firing temperature of early Xing porcelain leads to the dominance of a glassy phase within the glaze, and the high bonding strength of the glaze and body caused by the body–glaze interaction layer formed with dense anorthite crystals. Overall, these findings provide valuable insights into the firing technology in the Xing kiln and even in North China during the late sixth century. [ABSTRACT FROM AUTHOR]

Thirteen porcelains assigned to Sèvres factory productions and a few references to the other contemporary factories (Chantilly, Limoges, and Venice) have been studied on-site with a portable X-ray fluorescence (pXRF) spectrometer in order to control the provenance attribution. Characteristic XRF signals of major elements (Si, Ca, K, Pb) and minor/trace (Au, Bi, As, Ti, Co, Cu, Zn, Ni, Y, Zr, Rb, and Sr) elements are compared for the paste, blue mark, various glazed (colored) areas, and gilding. The comparison of peak intensities clearly distinguishes different types of hard- and soft-paste porcelain, made from either similar or distinct raw materials. The analysis of transition elements associated with cobalt identifies three types of cobalt blue and reveals that du Barry-style decoration on certain artifacts was typical of 19th-century production. On-site comprehensive studies of the two famous Etruscan-style breast bowls from Rambouillet Castle dairy, using pXRF and Raman spectroscopy, confirm the use of soft-paste porcelain for the cup and hard-paste for its support, providing detailed information on the use of gold nanoparticles in the burgundy-colored decoration.

During ceramic shaping, trapped oxygen increases porosity and reacts with elements to form unwanted compounds, enlarging pores. Excess phosphorus forms lumps, enhancing porosity and reducing density, leading to defects like increased brittleness, strength reduction, and improper densification, necessitating higher sintering temperatures. This study introduces extrusion-based 3D printing of a hybrid porcelain ceramic mixture with calcium silicide to achieve dephosphorization and deoxygenation while maintaining controlled sintering temperatures. Results show phosphorus is effectively removed at 1100°C and above sintering temperatures, while oxygen-related defects are reduced. Although calcium silicide does not lower the sintering temperature, it significantly improves porcelain purity, contributing to better material properties. These findings pave the way for enhanced additive manufacturing techniques in ceramic production. [ABSTRACT FROM AUTHOR]

Nine glazed porcelain artifacts bearing the coat of arms of France, from King Louis XV tableware orders, were analysed at the laboratory or in their conservation secure room. Based on the experience acquired in the study of 18th century European and Chinese porcelain using mobile XRF (pXRF) and Raman microspectroscopy, a comparison of the impurities in the paste (Y, Rb, and Sr), the elements associated with cobalt in the blue overglaze (Bi, Mn, Zn, and As) and those present in the tin yellow and Naples yellow pigments (Sn, Sb, and Zn) highlights the use of different raw materials for some of these objects. Differences regarding the Ag content in the gold decorations also provide information. Raman identification of the different types of yellow pigment confirms the categorization. The results obtained on the Louis XV tableware are compared to those of “Chine de commande”, attributed to the same places and periods of production or recognized copies. The clustering of the quantitative comparison pXRF signals of the abovementioned elements and a consideration of the Raman parameters of the yellow pigments appear to be effective tools for object categorization to confirm or refute questions about the authenticity of objects.

The compositional diversity of vitrified silicate ceramics has been quantified through multivariate statistical analysis and by means of specific chemical parameters of bodies. Distinct compositional spaces can be drawn for porcelains, porcelain stoneware, red stoneware, and silicate glass-ceramics. Porcelain and vitreous china bodies are strongly peraluminous with commonly a potassic character. A sharp boundary at ∼79 % alumosity separates them from porcelain stoneware bodies, which are peraluminous with a predominantly sodic character. The comparison of glazed versus unglazed porcelain stoneware revealed essential differences in iron content, but a deeper analysis is needed at the manufacturing district scale. Glass-ceramic bodies are peralkaline and low in silica. Red stoneware is characterized by Fe 2 O 3 content about 3–9 wt% and variable Na/K and alkali-to-alkali-earths ratios. The compositional gap between red stoneware and porcelain stoneware bodies (1.5 % < Fe 2 O 3 < 3 %), still unexploited by industry, is crucial to enable many resource efficiency and waste recycling actions. The formulation of waste-based silicate ceramics usually implies a shift of the chemical composition towards higher Fe 2 O 3 /Al 2 O 3 ratio and lower alkali-to-alkali earth ratio. This can lead to batches that fall outside the compositional space of porcelain or porcelain stoneware, opening to technological behaviour and technical performance that require further research.

Restorative dentistry often uses ceramic laminate veneers for aesthetic anterior teeth restorations due to their natural appearance and minimal invasiveness. However, the understanding of their clinical performance and how ceramic microstructure and processing affect longevity is limited. Objective: This study aimed to address this gap by determining the mechanical behavior, fracture load, and failure modes of CAD-CAM processed laminate veneers made of either lithium-disilicate-based glass ceramic (IPS e.max CAD) or feldspathic porcelain (Vita Mark II). It also aimed to develop a mechanical cycling methodology capable of determining the lifetime and failure modes of thin ceramic laminate veneers. Materials and Methods: Eighteen human maxillary central incisors were used to create the specimens. Minimal enamel preparation was required to ensure the proper adaptation of the thin ceramic laminates. Ceramic laminates made from lithium disilicate and feldspathic porcelain (Vita Mark II) were produced via CAD-CAM, with the final thicknesses less than 0.5 mm, then cemented with resin cement. Results: The mean fracture load for the glass ceramic was 431.8 ± 217.9 N, while for the porcelain, it was 454.4 ± 72.1 N. Failure modes differed considerably: porcelain showed more chipping, while lithium disilicate was associated with tooth structure failure. Conclusion: The material used did not significantly affect the fracture load of thin ceramic laminates in static tests. However, failure modes differed considerably. It was not possible to determine a set of mechanical cycling parameters that could establish the fatigue properties of thin ceramic laminates, as the maximum number of cycles reached was 536,818.

Pyroplastic deformation is still an important defect caused during firing in the manufacture of porcelain tiles when there is no control over the raw materials used in the formulation of ceramic tiles. The present study used mixing design as a tool in the development of pastes formulations for Brazilian porcelain tile manufacturing in order to reduce their pyroplastic deformation. Ceramic industry in Brazil has typical and complex way to set up porcelain tile formulations, using regularly more than a dozen raw materials. Therefore, the originality in this work was understanding the formulation by means of a pseudocomponent‐based approach (multiminerals triaxial diagram) and defining parameters that minimize that problem. Eleven different raw materials, supplied by Brazilian ceramic manufacturer, were used and characterized according to their physical–chemical properties. Later, raw materials were divided into three chemical categories and through a simplex‐centroid mixture design, defining the maximum limit of feldspar in 70%, 10 formulations in the experimental region were defined. All formulations were analyzed for particle size distribution, bulk density (postpressing and postburning), mechanical strength (postpressing and postfiring), thermal shrinkage, water absorption, and pyroplastic deformation. Thus, formulations that presented the most admissible behavior in the manufacture of porcelain tiles were selected, and tests were carried out for chemical, mineralogical, thermal (differential scanning calorimeter [DSC]/thermogravimetric [TG]), thermal expansion, porosity analysis, and optical fleximeter (pyroplasticity). All results were analyzed using response surfaces with data obtained by analysis of variance (ANOVA). Mixture design method proved to be a valuable tool to observe the behavior of raw materials and to optimization of Brazilian porcelain tile formulations. [ABSTRACT FROM AUTHOR]

Commonly referred to as a "porcelain gallbladder (PGB)," gallbladder calcification is usually asymptomatic. It is observed that chronic inflammation of the gallbladder can occur as a result of another underlying condition, specifically gallstone disease. In the past, there was a belief that PGB had a correlation with gallbladder cancer, with an incidence rate of 30%. However, recent studies have indicated that the rate is only 5%–22%. Patients diagnosed with PGB, who are deemed to be at an elevated risk of developing cancer may undergo prophylactic cholecystectomies. However, recent research indicates that a subset of these patients may potentially avoid this surgical intervention. As a result of the increased risk of gallbladder cancer, and the difficulty of holding and retracting the gallbladder, laparoscopic cholecystectomy was not often recommended for patients with PGBs in the past. However, with the advancement of technology laparoscopy is now a choice for such difficult cases. Here we report a case of PGB in a 55-year-old female patient who complained of intermittent pain in the right upper abdomen with vaginal discharge. She was successfully managed laparoscopically.

Background: The discoloration of endodontically treated anterior teeth poses a significant aesthetic concern for many individuals, impacting their confidence and self-image. Porcelain veneers have emerged as a popular solution for the aesthetic restoration of such teeth. This paper explores the role of porcelain veneers in addressing tooth discoloration, examining their efficacy, durability, and aesthetic outcomes via a clinical case. Case description: In this clinical case, an aesthetic restoration of a discolored central incisor was performed using a ceramic veneer. Due to the high degree of discoloration, an internal bleaching of the tooth was carried out prior to the final restoration. Various factors influencing the selection of porcelain veneers as a treatment modality, including shade matching, preparation techniques, and adhesive bonding, are discussed. Conclusions: The advancements in materials and techniques have enhanced the versatility and aesthetic appeal of porcelain veneers, making them a valuable option for achieving natural-looking and durable aesthetic restorations in individuals with discolored endodontically treated anterior teeth.

This study delves into the enigma arising from the utilization of porcelain dolls in the Chilean animated theater production Non Serviam: The Things You Need in One Place (2023). The presence of these dolls evokes an ambivalent sense of proximity and distance, fostering an exploration of the symbolic value of the doll figure, its function in childhood, and the unsettling impressions it may elicit. Such reflections serve as a starting point for examining the specific usage of three antique porcelain dolls in the aforementioned animated play and how their mystery is sustained.

Storch's work has been exhibited internationally and published in several photobooks, showcasing the unique perspectives of life in Greenland. [Extracted from the article]

This essay reads Sarah Orne Jewett's Deephaven (1877) to show how chinaware could be used to delineate American identity in late nineteenth-century fiction. As I show, china's aura of exoticism—reflected in its very name—could be deployed by regionalist writers to prop up local identity. Importantly, Jewett's characters make china the centerpiece of their bequeathals so that the foreign is the vehicle by which generations exert influence over the present. Chinaware's utility reifies the association of Asian identity with objectification. The town more generally appropriates Chinese signifiers and objects in their creation of a distinct spirit. I argue that towns perform this subsumption of the international in the service of the regional to position themselves in an intriguing position with regards to the national: distinct but also useful. Authors like Jewett show how the regional can, in part, deviate from the national by offering a tame and safe version of exoticism. The stakes of materiality thus include the determination of American belonging. [ABSTRACT FROM AUTHOR]

By analyzing the chromaticity values of the ancient blue-and-white porcelain combined with the imitated experiment, the color information is quantified and 'color dispersion' mechanism is clarified. Energy Dispersive X-Ray Fluorescence (EDXRF), field emission scanning electron microscopy (FE-SEM), the advanced focused ion beam transmission electron microscopy (FIB-TEM) technique, etc, were used to study the characteristics and the 'color dispersion' mechanism of the blue-and-white porcelain in Jingdezhen imperial kiln. The 'color dispersion' of the blue-and-white porcelain is mainly caused by Co-element structure stability, which is verified by the archaeological experiment results. Blue-and-white decoration lines diffusion length (named as 'color dispersion') are long (i.e. fuzzy) which has few or no spinel crystals in the body-glaze interaction layer of the blue-and-white porcelain. However, the blue and white porcelain with the clear lines has a large number of spinel crystals. The experimental results enrich the literature on the history of ceramic manufacturing techniques in Jingdezhen. [ABSTRACT FROM AUTHOR]

Art serves as a profound medium for individuals to express their innermost thoughts, experiences and emotions, holding considerable significance for both artists and audiences. It eases the meaningful exploration and communication of personal narratives and sentiments, highlighting the profound expressive capabilities within the realm of art. Taiwanese–Australian artist Ruth Ju-Shih Li presents a profound narrative through her contemporary ceramic art, particularly the captivating Metaphorical Flowers series since 2019. These works, resembling metaphorical self-portraits, encapsulate Li's spirituality using raw clay. Their 'ephemeral' nature, akin to abstract images of astral journeys, reflects the transient nature of human existence from a universal perspective. In contrast to conventional ceramics, Li's creations strike a delicate balance between intricate detail and inherent transience, crafted from raw, unfired clay. This unique approach challenges traditional notions of permanence in art, with sculptures often beginning to disintegrate during creation and exhibition, offering viewers a transformative experience as they witness the gradual collapse of her installations. Li's creative process extends beyond individual experiences to encompass the stories of others, allowing common emotions to be filtered through these narratives and transformed into varied forms that resonate with the audience. The narrative style she constructs creates a feeling of depth in the audience, with a form of expression that symbolizes the human life cycle. This evocative portrayal invites viewers to contemplate the transient nature of existence and the cyclical journey of life, adding a profound layer of meaning to her artworks. [ABSTRACT FROM AUTHOR]

The formation of defects, due to drying, in robocasted ceramic objects is an important issue arising from non-uniform shrinkage of the material during this step in the process. Common methods for shrinkage measurement are not well suited to the small size of robocasted cords or the complexity of robocasted objects. Innovative methods for shrinkage measurement were developed using non-destructive optical vision techniques with computer-controlled data acquisition, allowing measurement on millimetric cords and on specific zones of a product. The study of a single porcelain cord revealed an anisometric shrinkage related to the orientation of grains during extrusion. A differential shrinkage at the macroscopic scale was also measured on a robocasted object, indicating a moisture content gradient in the material. The methods presented in this paper are of particular relevance to real-time control of the drying process for robocasted objects. [ABSTRACT FROM AUTHOR]

When it comes to kennedy's class I or class II partially edentulous (distal extension cases) patients, retention is a problem. This problem can be overcome by incorporating precision attachments on the most distal abutment. This case report aims to help achieve a better understanding of selection of the type of precision attachment and incorporation of saggix precision attachment to achieve a successful cast partial denture with sufficient retention. A cast partial denture with saggix precision attachment was selected for this particular case keeping in mind the age, needs, economic, hygiene maintenance of the patient, number of abutments and health of remaining teeth. The patient was diagnosed with kennedy's class II modification space 3 edentulism in maxillary arch and complete edentulism in the mandibular arch. Following post and core build up in a couple of teeth, tooth preparation was done and porcelain fused metal crowns were given in the remaining teeth with a number of direct retainers and occlusal rest seats. A full palatal coverage cast partial denture with unilateral saggix attachment was given. This case report explains how a distal extension edentulous patient can be rehabilitated without any surgical procedures and in a much less time period using a cast partial denture with saggix attachment.

The origin of Ko-Kutani porcelain and its decoration style have been debated for over a century. Despite the well-established theory that identified the wares as the result of porcelain production in Kaga (present-day Ishikawa Prefecture) in the 17th century, there still is no general agreement as to where they were first incepted and fired. In recent years, curatorial traditional criteria have formed the basis upon which a new theory has been gaining popularity in Japan, identifying Arita (present-day Saga Prefecture) as their actual place of birth. Such a new theory, however, has proven insufficient to cast new light on many of the unexplained facts that characterize the history of the wares. Furthermore, scientific evidence has been lacking, as no systematic analyses of the porcelains were carried out until the present work. In order to define univocally the dynamics behind this period of Japanese history, the most important and complete Ko-Kutani collection extant in Japan today (Ishikawa Prefectural Museum of Art) was analyzed by portable X-ray fluorescence (pXRF). The scientific investigation was also extended to the very scarce shards excavated at the Kaga kiln site and Nonomura Ninsei's masterpieces. For the first time ever, the results herein presented clarify the missing points crucial to reaching a definitive conclusion. [ABSTRACT FROM AUTHOR]

Although information systems (IS) are increasingly used to provide sustainable solutions for tourism, our understanding of the social mechanisms whereby IS contribute to a sustainable visitor economy is limited. This paper fills the gap by investigating how organisations enact the affordances of IS in preserving intangible cultural heritage (ICH) to contribute to a sustainable visitor economy. Using an organisational aesthetics perspective, we explore the mechanisms through an in‐depth case study of an ICH‐based company in Jingdezhen, a famous historical porcelain city in China. Through the effective use of IS tools, the case organisation has successfully transformed from a ceramic manufacturing plant to a popular tourist attraction. Our study unveils six sustainable affordances of IS in three dimensions, wherein ICH aesthetics act as direct stimuli, knowledge tools and experiences. Affordances emerge from the processes of both creating and managing aesthetics. By enacting these affordances, the case organisation builds a more profound engagement with online audiences, attracts more ICH visitors and transfers ICH knowledge to potential inheritors of the tradition, creating a sustainable visitor economy. Our findings, summarised into a sustainable affordances model, contribute to the IS for sustainable tourism literature by shedding light on the black box of the social mechanisms of IS‐enabled ICH preservation. The sustainable affordances model can also help ICH‐based organisations reflect on how to build a sustainable visitor economy using IS. [ABSTRACT FROM AUTHOR]

The paper deals with glazed ceramics and porcelain from the sites of the Eastern Xia (Dong Xia) (1215–1234), found in Primorye. The artifacts under study are part of a group of prestigious items of the Jurchen population. The historical conditions for the formation of a changed regional settling model in the new state formation are characterized. The origin of glazed pottery and porcelain wares are analyzed, and the place they occupied in domestic and foreign trade among the Jurchens is explained. Items made in the Jin (1115–1234) and Southern Song (960–1279) kilns are considered separately. It has been established that after the conquest of Northern China, the Jurchens retained the production of kilns of Ding wares, Cizhou wares, Chün wares, Northern celadons, and items with colored lead glazes. Products made in kilns for producing Jian (temmoku) wares, Longquan celadon, and Ch'in-pai wares came to Jin from the Southern Song. The Song imperial style proved popular among the Jurchens. In general, the considered glazed ceramics and porcelain not only characterize trade relations in Jin on the eve of the formation of the Eastern Xia in 1215, but also the preferences of the Jurchen elite. The value of glazed ware increased as a result of the new political and economic situation.

Superhydrophobic materials have found extensive applications in everyday life and various industries due to their outstanding attributes such as waterproofing, exceptional anti-corrosion and self-cleaning capabilities. Nonetheless, their limited mechanical stability hinders their widespread use on ceramic surfaces. This study aims to address these limitations by employing industrial waste porcelain powder as a raw material and co-firing technology to create a micro-rough structure on ceramic surfaces. Furthermore, the impact of this rough structure on the wear resistance and hydrophobicity of the hydrophobic coating is investigated using the finite element method. The results indicate that the mechanical stability of the hydrophobic coating experiences a more pronounced enhancement with increasing distribution density of the micron rough structure of waste porcelain powder (WPPMRS). A dense rough structure does not only reduce its concentrated stress and improve its anti-wear ability, but also reduce the concentrated stress of hydrophobic coating to improve the protection of the coating. As a result, it substantially enhances the mechanical properties and stability of the hydrophobic coating. This work will provide valuable insights into the utilization of waste porcelain powder in sustainable superhydrophobic ceramics.
