The raw gypsum (chemical name dihydrate calcium sulfate) with the chemical formula CaSO 4 2H 2 O, is also known as dihydrate gypsum. Its theoretical components of CaO are 32.6%, SO 3 46.5% and H 2 O 20.9%.
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
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 -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, and its fineness and whiteness
The gypsum board of this measurement is suitable for structures and applications on large, heavy-duty sites, such as warehouses, factories, and production lines.
