Calcium sulfate hemihydrate

Description:
Calcium sulfate hemihydrate, commonly known as gypsum, is a chemical compound with the formula CaSO₄·0.5H₂O. It is characterized by its white, powdery appearance and is known for its ability to form a solid mass when mixed with water, a property that makes it widely used in construction and building materials, particularly in drywall and plaster. This compound is relatively stable under normal conditions but can dehydrate to form anhydrous calcium sulfate when heated. It is soluble in water to a limited extent, which allows it to be used in various applications, including as a soil conditioner and in the food industry as a coagulant. Gypsum also plays a role in the production of cement and is utilized in the manufacture of ceramics and as a filler in various products. Additionally, it has applications in the medical field, particularly in orthopedics for making casts. Overall, calcium sulfate hemihydrate is a versatile material with significant industrial and commercial importance.
