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 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 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.
Cobalt oxide is insoluble in water but soluble in acids.
[uses]
Cobalt oxide is mainly used as a pigment for colouring glass and frits.
Sometimes also used as catalyst or as a source for metallic cobalt.
[description]
Cobalt oxide is a is a harmful allergenic compound.
It is an inorganic compound and mostly found as tricobalt tetraoxide.
At room temperature is presented as a black odourless solid.
[classification]
Cobalt oxide is hazardous to the environment and harmful, if swallowed;
May cause sensitisation by skin contact and is toxic to aquatic organisms
Causing long-term adverse effects in aquatic environment
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.
