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. Formation of structure of glass-ceramic materials based on model glasses after thermal treatment has been investigated and the influence of phase composition on mechanical properties has been established. It was determined that the developed glass-ceramic materials are feasible for the application against the action of high-energy munitions with significant penetrating ability, especially when used in combination with ceramic elements.
