Conclusions The high-frequency smelting of a charge containing 69–75% Al2O3 and 31−25% SiO2 gives a product with a stable phase composition of mullite and glass. Corundum occurs only in the form of discrete crystals. Mullite from a charge with alumina modulus 3.0 contains a minimum of glass and a maximum of Al2O3, so that it is the most interesting one from the standpoint of refractories production. Firing the fused materials promotes the formation of mullite from the vitreous phase. A similar phenomenon occurs during the firing of products manufactured from fused mullite by the ceramics technology. In this case the pre-firing stage can be dispensed with.
