Gypsum Calcination

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 IUPAC defines calcination as "heating to high temperatures in air or oxygen" However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decompositionA calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature.
