Prospective directions for the creation of biologically active substitutes for bone tissue were analyzed. The effectiveness of the use of calcium phosphosilicate materials modified with CuO, ZnO, Ag2O, Fe2O3, TiO2, SrO and Nb2O5 to ensure high biocompatibility and antibacterial properties of bone endoprostheses has been established. The prospective use of lithium calcium phosphate silicate glass ceramics for obtaining strengthened, biologically active bone implants was substantiated. The main criteria for the development of biocompatible glass-ceramic materials regarding their composition, structure, texture, and surface properties have been established. The influence of differences in the structure and resorption of calcium phosphosilicate glass ceramics on the mechanism of formation of an apatite-like layer in vivo was analyzed. The features of mineralization of calcium phosphosilicate glass ceramics in vivo during bone tissue regeneration were determined, and the effectiveness of the use of glass ceramics based on hydroxyapatite and lithium disilicate in bone tissue replacement was established to reduce the rehabilitation period and long-term use of endoprostheses under variable loads. The developed OS-7 calcium phosphosilicate glass-ceramic material is characterized by the content of crystalline phases of 10 vol.% lithium disilicate and 55 vol.% hydroxyapatite with a ratio of CaO/P2O5=1.67, surface microrelief of 6 m, surface free energy value of 75 mJ/m2 and crack resistance of 6.0 MPam1/2. This material is biocompatible due to the formation of carbonate hydroxyapatite crystals already on the 14th day, which allows us to consider its promising use in the treatment of fractures, defects of long bones and in the replacement of short or tubular bones.

The prospects for the use of glass-ceramic materials as electrical products are analyzed. The priority of the formation of a self-organized macro- and nanostructure, glass-ceramic materials under conditions of low-temperature heat treatment to ensure their high physical and chemical properties is characterized. The effect of crystallization catalysts on the formation of the structure and viscosity of magnesium aluminosilicate glasses during their heat treatment is analyzed. The composition of magnesium aluminosilicate glass is optimized by using a combined crystallization catalyst in its composition, and an optimal heat treatment mode is established. The features of structure formation in magnesium-alumino silicate glass-ceramic materials are analyzed, which consist in the sequential course of the following stages: phase separation of glass by the spinodal mechanism $(\\mathbf{T}=800-850\\ {{}^{\\circ}}\\mathbf{C})$; nucleation of crystals of µ-cordierite $(\\mathbf{T}=850\\ {{}^{\\circ}}\\mathbf{C})$ and the formation of prismatic crystals of mulite $(\\mathbf{T}=1100\\ {{}^{\\circ}}\\mathbf{C})$, which are tightly connected. The formation of the nano- and submicron structure of the developed glass-ceramic material containing 80 vol. % mulite allows obtaining high physicochemical and electrical properties, which, along with its reduced weight, makes it promising for development as substrates in the design of a hybrid integrated circuit, vacuum-tight shell and capacitor dielectrics.

The polarization investigations of the anode behavior of titanium in mixed organic-&-aqueous fluoride-containing electrolytes have been carried out. The polarization curves constructed for electrode processes allow us to draw a conclusion that the simultaneous behavior of several processes is possible in the specified electrolytes and these processes include chemical etching of metal due to its interaction with solution components, electrochemical dissolution under polarization conditions and the formation of the oxide film due to the anode oxidation. The prevalence of one or other type of the process in this case is defined by the electrolyte composition and the electric electrolysis parameters. The obtained data serve as a basis for the development of the new method of combined etching that provides the homogenization of the titanium surface with simultaneous elimination of toxic reagents from the process or the reduction of their concentration.

The importance of preventing the spread of pathogenic microorganisms and viruses in the context of an intensifying pandemic and an unsatisfactory state of the environment has been analyzed. The necessity of application of antimicrobial materials with prolonged action to a wide range of pathogenic microorganisms has been established. The prospects of using antibacterial ceramic and glass materials and coatings with high performance characteristics and sanitary-technical properties have been determined. The expediency of the complex application of the method for determining the dehydrogenase activity of microorganisms and the diffusion method in the study of the antibacterial activity of glass coatings has been substantiated. The choice of glaze and bactericidal fillers for obtaining antibacterial glass-crystalline coatings with prolonged action for ceramic tiles has been justified. The antibacterial effect of the developed glazes and the potential need for their use to protect against pathogenic microorganisms in conditions of an increased risk of microbial load have been established.

Prospects for development of glass-ceramic materials on the lithium aluminosilicates base in order to increase the reliability of armor protection elements have been analyzed. Compositions of lithium aluminosilicate glasses with low content of lithium oxide have been developed, spodumene glass-ceramic materials were obtained on their base in conditions of low-temperature thermal treatment.

The efficiency of the use of IR spectroscopy in studying the structure of magnesium-aluminosilicate glass-ceramic materials was analyzed. It was established that the formation of the structure of these glass-ceramic materials during the heat treatment is associated with a distortion of the cordierite structure. The presence of solid solutions, high and low cordierite in the structure of the materials under study was detected according to the systems of bands F2, E2, C2 and D2, depending on the temperature of their heat treatment. The mechanism of phase formation in magnesium-aluminosilicate glass-ceramic materials has been determined, which consists in the formation of future crystals of -cordierite and spinel at the initial stages of nucleation, and crystals of -cordierite and mullite at the stage of crystallization. Formation of a finely dispersed glass-ceramic structure with a predominant content of -cordierite or mullite under conditions of low-temperature heat treatment is a decisive factor in ensuring high thermal and mechanical properties of glass-ceramic materials. This allows them to be used as structural elements of devices and equipment under thermal and mechanical loads.

Relevance of the development of high-strength glass-ceramic coatings obtained by resource-saving technology for protective elements has been established. Structure formation mechanism in magnesium aluminosilicate glasses during heat treatment has been analyzed. Selection of the system was substantiated, model glasses and glass-ceramic materials on its base have been developed. Patterns of structure regularity and formation of the phase composition of glass-ceramic materials during their ceramization have been investigated. It was established that the presence of crystalline phase of mullite after melting leads to formation of the primary crystals and allows the formation of the fine crystalline structure under conditions of the low-temperature heat treatment at the nucleation stage. Developed high-strength glass ceramic materials can be used as a base in creating protective elements for special-purpose vehicles by energy-saving technology.
