Cobalt blue, Ceramic color pigment stain

Complex inorganic color pigment (CICP) is crystallized color compound in solid solution produced by the calcination of two or more kinds of metal oxides including, Co, Cr, Fe or such transition metal element(s) at a very high temperature. It is also called calcined pigment or mixed metal oxides (MMO). CICP has a stable crystalline structure of rutile or spinel which provides outstanding properties, particularly heat resistance, weatherability and chemical resistance. CICP is widely used as colorants for ceramics, plastics and paints.
