Use of Gypsum. Gypsum is a widely used industrial material and building material. Gypsum (CaSO 4 2H 2 O) can be calcined and grinded to obtain β-type hemihydrate gypsum (2CaSO 4 H 2 O), that is, building gypsum, also known as cooked gypsum or plaster. The model gypsum can be obtained when the calcination temperature is 190 C, and its fineness and whiteness are higher than that of
