Effect of topaz on the synthesis of mullite in mixtures of kaolinite and alumina

Abstract

The synthesis of mullite in mixtures of kaolinite and alumina in the presence of small amounts of topaz is studied. Topaz is shown to activate the synthesis of both the primary (from kaolinite) and secondary mullite (through binding silica produced by thermal degradation of kaolinite), decrease the temperature of synthesis by 100°C, and increase the total yield of mullite. Products of the thermal degradation of topaz - mullite and gaseous chemically active fluoride compounds - are shown to play the role of mineralizing agents.
