Product Description

Product Description

Cobalt oxide (CO203) is a high -priced oxide of cobalt. The theoretical cobalt content is 71.06%, the oxygen content is 28.94%, and the density is 6.079/cm3. It is a black non -fixed powder, which will generate tetraoxide triangular (CO304) during heating. Cobalt oxide is a compound that is unstable and cannot be free. The cobalt oxide that is usually referred to is actually containing a certain number of tetraxide three cobalt. CO203 is stable only when it is hydrated, and this hydrophilicides will be dehydrated at 265 ° C to transform into an intermediate oxide tetraxide triple cobalt (CO304). Cobalt oxide can be restored by H2 to a tetraxid oxidation triple cobalt (CO304) at 125 ° C. At 200 ° C, it was restored to COO, and at 250 ° C, it was restored to metal cobalt. Cobalt oxide is insoluble in water, soluble in acid, and generates corresponding salt. 

Cobaltous oxide (cobaltous oxide), with the chemical formula CoO, is a metal oxide. It is a black-gray hexagonal crystal powder. It is insoluble in water, alcohol. It is easily reduced to metallic cobalt . It easily reacts with silicon dioxide and silica at high temperatures. Aluminum or zinc oxide reacts to produce a variety of pigments.
Cobalt oxide is an important transition metal oxide. Usually used as the main raw material for the production of cemented carbide, super heat-resistant alloys, insulating materials and magnetic materials, as well as catalysts and dyes in the chemical industry.
