Gypsum. Natural gypsum (CaSO4 • 2H2O), also known as gypsum, could be processed into β-hemihydrate gypsum (CaSO4 • 1 / 2H2O) by calcining and grinding, namely building gypsum, plaster or stucco. If the calcination temperature is 190 ° C, we can obtain model gypsum, whose fineness and whiteness is higher than construction gypsum.
