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.
Characteristic.
Cobalt powder is gray and irregular, soluble in acid, magnetic, easy to oxidize in wet air. It is widely used in aviation,
aerospace, electrical, mechanical manufacturing, chemical and ceramic industries. Cobalt based alloys or cobalt containing alloy steels are used as high temperature heat-resistant parts and important metal materials in atomic energy industry as blades, impeller, conduit, jet engine, rocket engine, missile component and chemical equipment of turbine.
As a binder in powder metallurgy, cobalt can ensure the toughness of the hard alloy. Magnetic alloys are indispensable materials in modern electronics and mechanical and electrical industries, which are used to make various components of sound, light, electricity and magnetic materials. Cobalt is also an important part of permanent magnetic alloys. In chemical industry, cobalt isused in high alloy and anticorrosive alloy, and also used in colored glass, pigment, enamel, catalyst and desiccant.
Application
-Water atomized cobalt powder has a relatively coarse grain size, which can be used in welding materials to improve its toughness, impact resistance and wear resistance.
-Reduced cobalt powder is in fine size and high purity, can be widely used in diamond tools, powder metallurgy,
Cobalt is a chemical element with symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal

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
1.The strongest oxidant and most active drier available.
2. It improves the surface drying and used in conjunction with auxiliary driers in oxidatively air-drying coatings. It is used in combination with lead or zirconium (together with calcium) depending on environmentally friendly formulations, and it improves the surface drying as well as through dry.
3. Common usage levels are between 0.02% to 0.05% based on metal on vehicle solids.
