Gypsum Rock / Gypsum Plaster Powder/ Natural Gypsum Rock

Gypsum is calcium sulfate di-hydrate, with the chemical formula CaSO4.2H2O. It is found in several crystalline formations in the Earth crust. It is extracted from the ground and used.

The color of Gypsum naturally is white. It may be seen in the colors of gray, blue, pink, or yellow due to impurities in the form of organic materials in clay or iron oxide.

Gypsum has a monoclinic crystallization system with a specific gravity of 2.2 and a hardness of 2. Gypsum mineral is crystallized in the form of fine and coarse grains; it is soluble in HCl acid and hot water. Pure gypsum contains 20.9% hydrated water and 6.46% SO

Gypsum purity is defined based on the percentage of gypsum mineral in it. According to the standards of American Society for Testing and Materials (ASTM), at least the purity required for gypsum in industrial materials is 70% of gypsum mineral, with most commercial gypsums having 75 to 99% purity. The impurities in gypsum are mostly shale, clays, calcium carbonates, and sometimes some organic materials.
