| Abstract: | The preparation of Cr2O3 fine powder by calcining CrO3 was reported. The effects of the temperature, time and the additives including the borate, oxides, dichromate and the combustible powder were researched. Under the conditions of 700 ℃ and 90 minutes, when 2%～3% of the combustible powder and the adequate water were added, it showed that the size of Cr2O3 powder was about 200 nm and its dispersivity was good. |
