Abstract

Fireclay ceramic materials based on the graphite-kaolin system were synthesized using graphite concentrate of Zakhchakhona site and enriched kaolin AKF-78 of the Angren deposit with refractoriness more than 1750 оС. The phase formation of crystals in the part of the graphite-kaolin system were studied by performing a synthesis in a Nitrogen at 1400 ° C in a tube furnace. The main crystalline phases in all compositions are mullite, sillimanite and graphite, in small amounts anorthite, cristobalite and aluminum nitride are present.
