Calcium Chromite, CaO.Cr2O3

Calcium Chromite, CaO.Cr2O3, is an olive-green crystalline powder of density 4.8 at 18° C. and hardness 6. It is produced by heating together calcium chloride and potassium dichromate, and subsequent extraction with concentrated hydrochloric acid. A compound, 2CaO.Cr2O3, is obtained by the interaction of ammonia and aqueous chrome alum and calcium chloride, while by direct combination of the oxides in the electric furnace, transparent green crystals of composition 4CaO.Cr2O3 are formed.
