Application: magnetic materials, electronic components materials, carbide materials, enamel glaze, color porcelain, glass, ceramic, cobalt catalyst and other cobalt salts.

 

Cobalt oxide is mainly used in the production of samarium cobalt alloy. Cobalt oxide is also used in the manufacture of hard alloys, magnetic materials, glass, enamel and ceramic pigments and glazes and other applications. Cobalt oxide coloring ability is very strong, but also a good colorant, it can make the porcelain glaze into a dark blue. The introduction of 0.002% CoO into the enamel can significantly Chemicalbook the coloring of the enamel, which is often used in production to make blue or black enamel. Cobalt oxide is also a raw material for the manufacture of cobalt blue, cobalt green and blue-green pigments. Cobalt oxide for industrial use can be produced by refining natural arsenocobalite and cobaltite. Natural cobaltite is a mixture of cobalt, nickel, zinc, etc. Cobalt oxides often contain impurities such as As, Cu, Fe, Mn, Ni, and Al.
