Name: Calcium sulphate Molecular Formula: CaSO4 CAS Registry Number : 7778-18-9 Calcium sulfate is a common laboratory and industrial chemical. In the form of -anhydrite, it is used as a desiccant. It is also used as a coagulant in products like tofu.In the natural state, unrefined calcium sulfate is a translucent, crystalline white rock. When sold as a color-indicating variant under the name Drierite, it appears blue or pink due to impregnation with cobalt chloride, which functions as a moisture indicator. The hemihydrateis better known as plaster of Paris, while the dihydrateoccurs naturally as gypsum. The anhydrous form occurs naturally as -anhydrite. Depending on the method of calcination of calcium sulfate dihydrate, specific hemihydrates are sometimes distinguished: alpha-hemihydrate and beta-hemihydrate.They appear to differ only in crystal size. Alpha-hemihydrate crystals are more prismatic than beta-hemihydrate crystals and, when mixed with water, form a much stronger and harder superstructure.
