METHOD OF PRODUCTION OF OXIDE HIGHLY REFRACTORY MATERIALS Russian patent published in 1998 - IPC

FIELD: manufacture of refractories; applicable in production of refractory raw materials - fillers, powders, pastes and cements. SUBSTANCE: the offered method includes blending of initial components including thermit additive - member of oxide of main initial component, ignition and heat treatment of mixture which is carried out by layer fusing, for instance, in agglomeration basin, during blowing of mixture layer with oxidizer (air, oxygen), cooling and grinding. Thermit additive ensures the needed temperature of mixture melting to form refractory materials of the needed phase composition. EFFECT: higher efficiency.
