Cobalt Chromite Blue pigment is cobalt chromite blue-green spinel (Co[Al,Cr]2O4) made by calcining at 2400°F a mixture of cobalt (II) oxide, chromium (III) oxide, and aluminum (III) oxide in varied ratios forming a interdiffused crystalline spinel matrix. Its constitution may also include one or more of the modifiers ZnO, MgO, SiO2, TiO2, and/or ZrO2 to adjust color hue or other properties. Cobalt blue pigments are the most durable blue pigments commercially available. They have excellent chemical and heat stability, and can be used in chemically aggressive environments and exterior durable applications without color fade.
