METHOD OF PRODUCING CERAMIC MATERIAL FROM ALUMINIUM TITANATE (TONATNOX - T) Russian patent published in 1995 - IPC

Abstract RU 2046782 C1

FIELD: technology of ceramics producing. SUBSTANCE: method involves mixing titanium dioxide, titanium nitride and aluminium nitride powder taken at the ratio, wt.-% aluminium nitride 50.9-58.9; titanium nitride 0.1-43.0, and titanium dioxide 0.1-49.0 followed by their combined roasting, blank forming and roasting in oxygen-containing atmosphere up to ceasing blank mass change. After cooling reaction-caked monophase ceramic material made of aluminium titanate is obtained. The yield is increased up to 126% This ceramic material shows finely grained structure. EFFECT: increased strength at decreased values of heat expansion linear coefficient. 1 tbl
