High-temperature interactions between calcium and strontium titanodisilicates have been investigated. The formation of two limited series of tetragonal solid solutions based on these initial compounds was established. The discontinuous nature of changes in the physicochemical properties of solid solutions, depending on the composition, has been determined. Glasses and glass-crystalline materials based on the studied system Ca 2 TiSi 2 O 8 - Sr 2 TiSi 2 O 8 , and the characteristic features of glass crystallization and the temperature limits of the existence of the crystalline phase have been elucidated. Tab. 1, ill. 2, bibliography: 5 titles.
