FIELD: chemistry.
SUBSTANCE: method of producing alpha-phase of aluminium oxide includes distillation purification of aluminium alcoholate, hydrolysis thereof and synthesis of alpha-phase of aluminium oxide. Distillation purification of the aluminium alcoholate is carried out in a current of inert gas, and hydrolysis of the aluminium alcoholate and synthesis of the alpha-phase of aluminium oxide is carried out in a supercritical reactor.
EFFECT: method increases degree of purity of the alpha-phase of aluminium oxide, increases output and reduces power consumption per unit product while increasing packed density of the alpha-phase of aluminium oxide.
