Cobalt Oxide

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.

Cobalt oxide is a consistent, reliable oxide and a common colorant in pottery.
It is available in powdered form and is blackish in color.

It is a very strong oxide, and using very small quantities yields bright, intense blues.
In ceramics, cobalt oxide is used mainly in slips, washes and glazes and can be applied through brushwork, decals or other surface decorating techniques.

It can also be added to porcelain or stoneware clay. Because cobalt oxide is not as finely powdered as cobalt carbonate, cobalt oxide is more likely to create blue specks, a quality that we believe can be quite beautiful!

Because of the strength of this oxide as a colorant, glazes containing cobalt can produce halos and flashing during firings.

High Quality CAS 12190-79-3 Cobalt Oxide for Lithium Battery Cathode Material

Lithium cobalt oxide, also known as lithium cobalt oxide, chemical formula LiCoO2, is an inorganic compound that is generally used as a positive electrode material for lithium-ion batteries. The structure of LiCoO2 has been studied by X-ray diffraction, electron microscopy and neutron powder diffraction. The lithium atomic layer lies between plates of regular octahedrons formed by cobalt and oxygen atoms (shown below). This structure is in agreement with the structure predicted by the theory. Lithium cobalt oxide is toxic and should be handled safely.
