METHOD OF PREPARING ALUMINIUM OXIDE POWDER

摘要

FIELD: chemical industry. SUBSTANCE: aluminium wire with diameter of 07001<d<0.035 cm is inserted into gap between electrodes in oxygen containing medium, and pulse of electric current with density of <EMI ID=0.205 HE=6 WI=60 TI=CHI> is passed to produce aluminium oxide powder having specific area of 96-163 sq.m/g. EFFECT: more efficient preparation method. 1 tbls
