The invention relates to a method for producing cobaltosic oxide. The obtained cobaltosic oxide has a large specific surface area and good microscopic consistency. The method for producing the cobaltosic oxide comprises the following step of: calcining cobalt carbonate or cobalt hydroxide in an air atmosphere at the temperature of between 400 and 800 DEG C for 0.5 to 5 hours to obtain the cobaltosic oxide. As a preferable scheme of the invention, the calcination is performed in a rotary kiln, wherein the outer side of a furnace tube of the rotary kiln is provided with an electrical heating element. The method has the advantages that: 1, the method has low energy consumption because each ton of cobaltosic oxide consumes 1,000 to 1,500 degrees of electricity; 2, a cobaltosic oxide product has a large specific surface area and relatively high activity; 3, automatic material feeding and discharging can be realized; 4, metal zirconium, titanium or the oxide thereof or a ceramic material istaken ...
