Widely used in construction and building materials, calcium sulfate hemihydrate is primarily known for its role in producing plaster of Paris. When mixed with water, it rehydrates and hardens into a solid mass, making it ideal for casting, molding, and sculpting in art and construction. It is a key component in drywall and wall plasters due to its fire-resistant properties and ability to form smooth finishes. In dentistry, it serves as a model material for making dental casts and impressions. The material is also used in orthopedics for setting broken bones with plaster casts. Additionally, it finds use in agriculture as a soil conditioner to improve soil structure and supply sulfur and calcium without altering pH significantly. In food production, it acts as a coagulant in tofu manufacturing and as a dietary calcium source.
