Cobalt oxide (II) or cobalt monoxide are inorganic compounds that appear as olive or red crystals, or as a gray or black powder. It is widely used in the ceramic industry as an additive to create blue enamels and enamels, as well as in the chemical industry to produce cobalt (II) salts.


Cobalt oxide (II) has been used for centuries as a dye in oven ceramics. The additive provides an intense blue tone called cobalt blue. The space between the bands (CoO) is about 2.4 eV. [citation needed] It is also used in cobalt blue glass.
