    Specification (% )

    Basic information:

    1.Molecular formula: Co3O4
    2.Molecular weight: 240.797
    3.CAS No.: 1308-06-1
    4.Purity: Co:72%min
    5.Storage: Keep the receptacle sealed and stored in a cool and dry place, and ensure that the working room has good ventilation or exhaust device.

    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, nitric acid and hydrochloric acid at room temperature. When heated above 1200 ℃, it will decompose into cobaltous oxide. When it is strongly heated to 900℃ in a hydrogen flame, it is reduced to metal cobalt.
