Research in the Area of Preparing Materials Based on Fuzed Quartz HCBS. Part 8. Effect of Alkali Additions on Ceramic Sintering and Cristobalitization in a Nonisothermal Heating Regime1

Abstract

Results are provided for a study of the effect of alkali additions based on dispersed silicate lump (sodium metasilicate) on quartz ceramic sintering and cristobalitization in a nonisothermal heating regime in a high-temperature dilatometer. Depending on additive content the difference in initial sintering temperature reaches 300°C, and for the initial stage of cristobalitization it reaches 400°C.
