Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.
The gypsum, casting gypsum and pre-products gypsum are commonly used in construction. The wet calcining is hearting under the water vapor pressure in the autoclave or in the low pressure, boiling point higher than 100℃ of the salt solution. Then produces α-hemihydrate gypsum, the basis material to cast a special gypsum.
