Cobalt trioxide is a black cubic crystal with spinel structure. Insoluble in water, almost insoluble in acid, micropowder can slowly dissolve in acid. Chemicalbook releases oxygen in the air from 750 ° C and transforms into CoO at 900 ~ 950 ° C.
Cobalt Tetroxide is similar to ferroferric oxide, and can be approximately regarded as a compound formed by cobalt oxide (CoO) and cobalt oxide (Co2O3). Black or grayish black powder. The apparent density is 0.5-1.5g/cm3, and the tap density is 2.0-3.0g/cm3. Cobalt Tetroxide can be slowly dissolved in hot sulfuric acid, but it is insoluble in water, at room temperature. When heated above 1200 ºC, it will decompose into cobaltous oxide. When it is strongly heated to 900ºC in a hydrogen flame, it is reduced to metal cobalt.
