Solid Solutions Formation Mechanism in Cordierite-Mullite Glass Materials During Ceramization

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.

Research of block polymerization of 2-hydroxyethylmethacrylate in the presence of polyvinylpyrolidone and mineral filler based on silicon oxide and aluminum

The patterns of obtaining in a block of porous composites based on copolymers of 2-hydroxyethylmethacrylate with polyvinylpyrrolidone in the presence of mineral fillers - glass ceramics based on silicon oxides and aluminum were investigated. We have estimated the impact of the amount and the size of inorganic filler, temperature and initiator on the polymerization rate and «maximum» monomer conversion. The results will be used to improve the technology for producing osteoplastic porous composites.

Glass-Ceramic Materials on the Lithium Disilicate Basis: Achievements and Development Prospects

The current state of developments and the prospects of using glass-ceramics based on lithium disilicate were analyzed. The choice of R2O–RO–RO2–R2O3–P2O5–SiO2 system for model glasses was justified. The structure of glasses after heat treatment in connection with their physico-chemical properties was studied. The developed lithiumsilicate glass-ceramic materials were characterized by high performance properties and can be used as transparent armor.
