Cobalt oxide (Co2O3) 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 (Co3O4) 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 (Co3O4). Cobalt oxide can be restored by H2 to a tetraxid
oxidation triple cobalt (Co3O4) 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.
