Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
Powder process technology: Gypsum is monoclinic system, with a high degree of cleavage, easily split into thin slices. When gypsum is heated to 100 ~ 200 ° C, it loses some crystal wate, and hemihydrate gypsum appears. α-hemihydrate gypsum crystal is good and solid; β-hemihydrate gypsum is flaky and cracked, with small crystal and high specific surface area than the α-hemihydrate gypsum.
