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, …
