Evaluation of Crystallization Capacity of Glasses

A temperature-concentration dependence of the linear velocity of crystal growth (LVCG) of diopside for potassium-bearing glasses of the system CaO – MgO(Al2O3) – SiO2 is determined based on adaptation of the Turnbull-Cohen theoretical equation, and a relationship between the LVCG of devitrite and cristobalite and the chemical composition of glasses located in the respective areas on the phase diagram of the Na2O – CaO – SiO2 system phase diagram is established.
