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.

We are able to supply Tin in many forms including LME registered and non registered, ingots, slabs, bars, foil, granules, powder, anodized activated powder, shot, wire, sticks, ingots, and “mossy tin”. Tin is a silvery-white metal, is malleable, somewhat ductile, and has a highly crystalline structure. The element has two colours, with a cubic structure which changes at allotropic forms. On warming it is grey, the ordinary form of the metal. When Tin is cooled below 13.2°C, it changes slowly from white to grey or tetragonal structure. This change is affected by impurities such as Aluminium and Zinc, and can be prevented by small additions of Antimony or Bismuth.
We put forward a high quality of assortment of Nickel which is available in many forms including LME registered and non registered cathodes, cut cathodes, briquettes, pellets, disks, shots, granules, foil, powder, flakes, sheet, wire, mesh, spheres, “evaporation slugs”, and rods. Nickel is a silvery white metal that takes on a high polish. It is hard, malleable, ductile, somewhat ferromagnetic, and a fair conductor of heat and electricity

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. [formula] Co3o4 [cas registry number] 1308-06-1 [synonyms] Cobalt oxide 73%, cobalt oxide frit grade. Black cobalt. Tricobalt tetraoxide. [appearance] Cobalt oxide occurs as a grey to black powder. [solubility] 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
