Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO4 and related hydrates. In the form of lanhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum.It has many uses in industry. All forms are white solids that are poorly soluble in water. Calcium sulfate causes permanent hardness in water.
The main use of calcium sulfate is to produce plaster of Paris and stucco. These applications exploit the fact that calcium sulfate which has been powdered and calcined forms a moldable paste upon hydration and hardens as crystalline calcium sulfate dihydrate. It is also convenient that calcium sulfate is poorly soluble in water and does not readily dissolve in contact with water after its solidification.

Calcium sulfate, a chemical compound with the formula CaSO4, exists in various forms, but the two most common ones are gypsum (calcium sulfate dihydrate) and anhydrite (calcium sulfate anhydrous). Gypsum is a soft, white mineral often used in construction and agriculture. It is a key ingredient in plasterboard, where it provides fire resistance and soundproofing. In agriculture, gypsum is employed to improve soil structure and nutrient retention. Anhydrite, on the other hand, is a denser, less water-absorbent form of calcium sulfate and is used in industrial processes, including cement production. Both forms of calcium sulfate have distinct properties that make them valuable in a range of applications, from building materials to industrial chemistry.
