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, n itric acid and h ydrochloric acid at room temperature. When heated above 1200 C, it will decompose into cobaltous oxide. When it is strongly heated to 900C in a hydrogen flame, it is reduced to metal cobalt.

escription:
This is obtained as an olive-green powder by heating the metal in air or steam or by thermal decomposition of the hydroxide, carbonate or nitrate. It has the sodium chloride lattice and is antiferromagnetic below 292�°K. When heated in oxygen above 400�° the black oxide Co3O4 is obtained. This oxide is isomorphous with magnetite Fe3O4, and has tetrahedrally surrounded cobalt(II) ions and octahedrally surrounded cobalt(III) ions. Both these oxides are readily reduced to the metal by heating in hydrogen or with carbon. The reactions of CoO with silica, alumina and zinc oxide are used to form pigments in the ceramic industry.

Application:
Mainly used for glass, enamel, ceramic, magnetic materials such as dense agent, azure blue, cobalt blue, cobalt green color colorant, catalyst, livestock nutrition agent. It is also used in the preparation of cobalt salts.
In pigments for ceramics; glass coloring and decolorization; oxidation catalyst for drying oils, fast-drying paints and varnishes; preparation of cobalt-metal catalysts, Co powder for binder in sintered tungsten carbide; in semiconductors.

Cobalt oxide (Co203) is an expensive cobalt oxide with a theoretical cobalt content of 71.06%, an oxygen content of 28.94%, and a density of 6.079/cm3. It is a black amorphous powder that generates cobalt oxide (Co304) after heating. Cobalt oxide is an unstable compound and cannot be freed. The cobalt oxide commonly referred to actually still contains a certain amount of cobalt tetraoxide. Co203 is only stable in a hydrated state. This hydrate will dehydrate and transform into the intermediate oxide cobalt tetraoxide (Co304) at 265�??�?�°C. Cobalt oxide is reduced to cobalt tetraoxide (Co304) by H2 at 125�??�?�°C, reduced to CoO at 200�??�?�°C, and reduced to cobalt metal at 250�??�?�°C. Cobalt oxide is insoluble in water. After dissolving in water, it decomposes into hydrates when it encounters water. It is insoluble in water, but soluble in acid and forms corresponding salts.
