Characteristic
Cobalt(II) oxide or cobalt monoxide is an inorganic compound that appears as olive-green to red crystals, or as a greyish or black powder.soluble in acid, insoluble in water, alcohol, ammonia.Readily reduced by carbon monoxide to cobalt metal.It is easy to react with silica, alumina or zinc oxide at high temperature to produce various pigments.
Chemical formula：CoO
Molar mass：74.9326 g/mol
Appearance：black powder
Odor：odorless
Density：6.44 g/cm3
Melting point：1,933 °C (3,511 °F; 2,206 K)
Solubility in water：insoluble in water
Magnetic susceptibility (χ)：+4900.0·10−6 cm3/mol
Crystal structure：cubic, cF8
Application
Cobalt(II) oxide has for centuries used as a coloring agent on kiln fired pottery. The additive provides a deep shade of blue named cobalt blue. The band gap (CoO) is around 2.4 eV. It also is used in cobalt blue glass.
