This research study investigates the potential use of traditional raw materials to synthesize new ceramic composite materials that can be used in different industrial applications. The composite materials were developed through mechanical activation, carbonization, and reactive sintering techniques. Natural zeolite from Tokaj region, alumina from Motim, and sawdust were used as starting raw materials. Stoichiometric amounts of the raw materials were mixed and milled in planetary ball milling followed by uniaxially pressing to produce cylindrical ceramic discs. The produced green ceramics were then sintered in an electric laboratory kiln under an oxygen-free environment at 1200 °C. In-situ carbonization of the sawdust was confirmed via X-ray diffraction. The thermal properties were also investigated by derivatography. The produced ceramic specimens were tested on microstructural characteristics, porosity, density, and water absorption.

The authors have examined how the properties are changing using different sintering temperature based on the kaolin. Kaolin powder and a mixture of kaolin and 10 m% alumina was made and measured their sintering properties (TG, DTG, DTA, height). Pellets were compacted from the powders and sintered at 450 °C, 575 °C, 775 °C, 870 °C, 1100 °C temperature. The volume shrinkage, sintering weight losses, microstructure and phase composition of sintered specimens were investigated. In the case of sintering at 450 °C the volume of the samples increased; with a further increase of the temperature a continuous volume decrease can be observed. [ABSTRACT FROM AUTHOR]

In the present research work is studied and described the influence of alumina and zirconia powders on physical and mechanical properties of the conventional ceramic floor tiles. After testing several different raw material compositions the authors have found that adding 5 m% commercial ZrO2 powders the shear strengths and pressure strengths of these floor tiles can be considerable increased. These new floor tiles with increased mechanical strengths may be suitable for use in dairy, meat, food and other industries. [ABSTRACT FROM AUTHOR]
