Abstract

This paper presents the results of a study obtained using the developed quantitative method for determining the crystallization resistance of quartz glass produced from quartz concentrates derived from natural quartz raw materials of different origins. It is shown that the onset temperature and kinetics of quartz glass crystallization depend not only on the purity of the quartz concentrates from which the quartz glass is melted but also on the genesis of the original quartz. Glasses obtained from superquartzites of the Eastern Sayan exhibit a higher resistance to crystallization than glasses produced from granulated quartz of the Kyshtym deposit (Urals), which indicates a significant advantage of quartzites in the production of heat-resistant quartz ceramics and crucibles for growing silicon.
