FIELD: production of aluminum alpha-oxide. SUBSTANCE: aluminum alpha-oxide with crystal size of less than 1 mcm is produced by preliminary production of carbonized aluminum alpha-oxide and subsequent treatment with oxygen- containing gas at 1100-1250 C up to full burning out of carbon. Oxygen-containing gas is used in form of air. EFFECT: simplified process and reduced power consumption. 2 cl
