The processes of crystallization and sintering, occurring during firing, during the production of strontium-anorthite glass-ceramics by the method of powder technology, have been studied. The character of the influence of the dispersity of the initial glass powders and the temperature-time conditions of firing on the temperature and heat of crystallization, the nature of the precipitated phases, the temperature range and the kinetics of particle sintering is shown. It has been revealed that for the glass composition undergoing vitrification, there is a narrow range of powder dispersion, on the basis of which, using a multistage heat treatment regime, it is possible to obtain densely sintered materials of the required composition with high mechanical characteristics.
