Abstract
The processes of phase formation in refractory clay in the presence of topaz-bearing rock additives are investigated. It is established that the effect of topaz proper is determined by its quantity. Topaz in low quantities (up to 0.5 - 1.0%) intensifies the formation of primary and secondary mullite of prismatic habitus, lovers the temperature of mullite synthesis, and improves the mullite structure. An increase in the topaz content ever 25% is accompanied by the formation of mullite of needle-shaped habitus, in addition to prismatic mullite.
