Mechanical Activation of Refractory Glass-Ceramic Batches

摘要

Most of technical glass ceramics are synthesized based on alkali-free or low-alkali aluminosilicate systems characterized by high refractoriness: the melting point of a glass-ceramic melt often exceeds 1600— 1650°C. Glass melting at such high temperatures is complicated by a number of technical and technological difficulties and is accompanied by high fuel and energy consumption. Moreover, the high aggressiveness of glass-ceramic melts to refractories at elevated temperatures leads to extremely intense corrosion of the refractory brickwork of a glass-melting furnace and to a decrease in its overhaul life. In this context, an urgent task is to develop methods for intensifying glass melting and reducing the temperatures of production of melts of refractory glass ceramics.
