What Is Cobalt Oxide?

Cobalt Oxide, also known as Cobaltous Oxide, is an inorganic cobalt compound with the chemical formula CoO. It is one of the stable oxides of cobalt and is widely used as a cobalt source in industrial production.It has a relative density of approximately 6.45 and exhibits good chemical stability under normal conditions.

Cobalt Oxide is insoluble in water, alcohol, and ammonia, but it can dissolve in acids to form cobalt-containing solutions. Under reducing conditions, it can be reduced by carbon monoxide to produce metallic cobalt. At high temperatures, Cobalt Oxide can react with silica, alumina, or zinc oxide to produce different cobalt-containing pigments.

Due to these chemical characteristics, Cobalt Oxide is widely used as a raw material in ceramics, catalysts, coatings, and battery-related applications.
