high-strength

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.

The perspective of glass-ceramic high-strength materials used for personal armor elements has been established. The methodological approach has been developed and the choice of initial lithium aluminosilicate system for obtaining high-strength lightweight glass-ceramic materials has been substantiated. The glass formation area in the chosen system was studied, and model glasses were synthesized. Features of crystal structure formation during heat treatment of the developed model glasses were investigated. As a result, high-strength glass-ceramic materials have been developed.
