The low level of complexity in the processing of raw materials at mining and processing enterprises adversely affect the environment causing considerable damage to it. Meanwhile technological waste is a cheap source of raw materials for liquid products of functional purpose, particularly inorganic filler which are widely used in the manufacture of paints and building materials, paper, plastics, insulating and protective materials. Improved performance and physical and chemical properties of materials are achieved by optimizing the composition and dispersion of the particles. By the example of the research subjects received from the flotation waste nepheline ore-dressing, it has been shown that a high degree of homogenization to obtain fine mixtures (75 % of 3–4 micron fraction) composite filler powders the ultrafine grinding method achieved by using a planetary ball mill for a short period of time (at least 1 hours). The use of other grinding methods, for example by means of ball mill or a vibration such effect is not obtained. At the conditions of ultrafine grinding the ionization and amorphization of the surface layer of powder material particles (mechanical activated processing) are occurred. This increases its activity by reacting with organic and inorganic binding, and provides high performance. The obtained filler has been tested in the composition of temperature-controlled sealants and glues used in the aerospace industry, shipbuilding and electronics. To obtain such materials sphene and nepheline received from industrial tailings of Khibiny apatite-nepheline ore deposits are used

The metastable structure state of the anatase phase of titanium dioxide has been shown to be a favorable basis for a targeted influence on it with the aim of producing new oxide phases consisting of nanoparticles and, accordingly, having a new combination of properties. Mechanical activation and subsequent annealing of the activated powders result in a sequence of phase transformations (anatase–brookite–rutile), thereby ensuring structural ordering of titanium dioxide. Transformations of the titanium oxide phases have been studied in detail by X-ray diffraction. We have evaluated the crystallite (coherent scattering domain) size and internal strain (ε) from diffraction line broadening by profile fitting with the pseudo-Voigt function. The average particle size was 20 nm after mechanical activation, whereas heat treatment increased it by almost a factor of 2. Similar results have been obtained for internal strain. The pore system of the particles is formed by mesopores. The hysteresis loop observed in nitrogen sorption–desorption isotherms suggests that the titanium dioxide particles have platelike morphology. The results obtained in this study have been used to develop innovative technology of a special grade of titanium dioxide for the preparation of thermally stable glues with dielectric properties and high tensile and shear strength.
