KobaltIIOxid

KobaltIIOxid, also known as cobalt(II) oxide, has the chemical formula CoO. It is an inorganic compound that appears as a green powder. This compound is a semiconductor and exhibits antiferromagnetic properties at low temperatures. KobaltIIOxid is produced commercially through the reduction of cobalt(III) oxide or cobalt(II,III) oxide with hydrogen or carbon monoxide at elevated temperatures. It can also be formed by the thermal decomposition of cobalt(II) carbonate or cobalt(II) hydroxide in the absence of oxygen.

The primary uses of KobaltIIOxid are in the production of other cobalt compounds, such as cobalt salts, and as a pigment in ceramics and glass. Its green color makes it valuable for coloring glazes and enamels. In industrial applications, it serves as a catalyst in various chemical reactions, including oxidation processes. KobaltIIOxid can also be used in the manufacturing of lithium-ion battery cathodes, although other cobalt oxides are more prevalent in this application. The compound is insoluble in water but dissolves in acids to form cobalt(II) salts.
