Cobalt chromite blue green spinel

Cobalt chromite blue green spinel is an inorganic pigment that is the reaction product of high temperature calcination in which aluminum oxide, chromium (III) oxide, and cobalt (II) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of spinel. Its composition may include any one or a combination of the modifiers MgO, SiO2, ZnO, or ZrO2.
