Crystallization and sintering, which occur during firing, during the production of strontium-anortite glass ceramics by means of powder metallurgy are studied. It is shown that the dispersity of the initial glass powder and the temperature–time firing regimes affect the crystallization temperature and heat, the nature of the precipitating phases and the sintering temperature interval and kinetics of the particles. It is determined that for ceramizing glass compositions there exists a narrow powder dispersity interval in which densely sintered materials with the required composition and high mechanical properties can be obtained using multistep heat-treatment.
