Cobaltous oxide (cobaltous oxide), with the chemical formula CoO, is a metal oxide. It is a black-gray hexagonal crystal powder. It is insoluble in water, alcohol. It is easily reduced to metallic cobalt . It easily reacts with silicon dioxide and silica at high temperatures. Aluminum or zinc oxide reacts to produce a variety of pigments.
Cobalt oxide is an important transition metal oxide. Usually used as the main raw material for the production of cemented carbide, super heat-resistant alloys, insulating materials and magnetic materials, as well as catalysts and dyes in the chemical industry.Assay(Co) | 72%min |
