Requirements placed on the quartzite-based lining of crucible-type induction furnaces are discussed. The properties of Pervoural'skii and Karel'skii quartzites (P- and K-quartzites) are studied. Mineral impurities (in particular, mica) and their effect on properties of quartzite mixtures are considered. Industrial tests show that the fine-grained, predominantly intergranular mica is mainly responsible for the high wear resistance of K-quartzites. A characterization of the Metchangjarvi quartzite deposit is given and its commercial potential for production of refractory materials is discussed.
