Cobalt Hydroxide use in ceramics and glass production

Cobalt hydroxide is an inorganic substance, chemical formula Co(OH)2, rose red monoclinic or hexagonal crystal system, insoluble in water, slightly amphoteric, difficult to dissolve in strong alkali, but soluble in acid and ammonium salt solution. The density is about 3.6g/cm³. Melting point 1100-1200℃, for amphoteric hydroxide. It is mainly used as a colorant for glass and enamel, as a raw material for other cobalt compounds, and as a desiccant for varnishes and coatings.
