Strontium-alumosilicate glassceramics synthesis using batch mechanoactivation

The influence of mechanical activation of the charge on the glass-making process and the homogeneity of the obtained glass is considered. The object of research is refractory sitall glass. Mechanical activation of the charge was carried out by fine grinding it in a planetary mill to a specific surface area of ??the resulting powder of 0.9 m ² / g. It is shown that in the activated charge the processes of silicate and glass formation are shifted by 50 - 150 ° C towards lower temperatures. A mechanically activated charge makes it possible to synthesize a glass that is more homogeneous in composition than an unactivated charge, which ensures the production of a sitall with a highly homogeneous glass-crystalline structure.
