As Ceramic Pigments, Cobalt Oxide 72%
Cobalt oxide is a metallic pigment that provides blue coloring in porcelains and glass. Various forms of cobalt oxide are changes to CoO at 850 - 900 C. CoO is a grayish brown powder that decomposes at 1935 C, insoluble in water. It is also used as a drying agent in inks and varnishes and as a feed and fertilizer additive. Cobalt carbonate has same coloring application as it decomposes to cobalt oxide at high temperature. Cobalt carbonate tends to disperse better in a glaze but can produce blisters because of the CO2 gas presence at high temperature. Commercial grades of cobalt carbonate are the complex of carbonate and hydroxide such as cobalt carbonate hydroxide (1:1) (CAS RN: 12069-68-0), Cobalt carbonate hydroxide (2:3) (CAS RN: 12602-23-2), and cobalt carbonate hydroxide (2:3) monohydrate
(CAS RN: 51839-24-8).
Properties: It is a kind of light pink powder, specific gravity 3.597, soluble in acid and ammonium salt solution, insoluble in water and alkali. It reacts with organic acids to form cobalt soap.
