Calcium sulfate dihydrate

Description:
Calcium sulfate dihydrate, commonly known as gypsum, is a chemical compound with the formula CaSO₄·2H₂O. It is a white or colorless crystalline solid that is soluble in water to a limited extent. Gypsum is characterized by its relatively low density and is often found in sedimentary rock formations. It has a monoclinic crystal system and exhibits a variety of physical forms, including massive, fibrous, and granular. The compound is widely used in construction as a key ingredient in drywall and plaster, as well as in agriculture as a soil conditioner. Additionally, it plays a role in various industrial processes, including the production of cement and as a filler in products like paints and plastics. Gypsum is also utilized in the food industry as a coagulant and in the production of tofu. Its thermal stability allows it to be heated to form anhydrous calcium sulfate, which is used in various applications. Overall, calcium sulfate dihydrate is an important material with diverse applications across multiple industries.
