Anhydrous Sulfate of Lime, also known as calcium sulfate hemihydrate or simply hemihydrate, is a chemical compound with the molecular formula CaSO4·½H2O. It is a white, odorless, crystalline solid that occurs naturally as gypsum or can be produced synthetically.
As the term suggests, anhydrous refers to the absence of water molecules. In the case of Anhydrous Sulfate of Lime, it means that the compound does not contain any water molecules in its structure. This distinguishes it from other forms of calcium sulfate, such as dihydrate (CaSO4·2H2O), commonly known as plaster of Paris, which contains two water molecules for every calcium sulfate molecule.
Anhydrous Sulfate of Lime finds various industrial applications. It is primarily utilized in construction as a binding agent in the production of plaster, cement, and drywall. It plays a crucial role in the setting and hardening process of these materials. Moreover, it is also used as a soil conditioner in agriculture to improve the calcium content and adjust pH levels.
In addition to its industrial uses, Anhydrous Sulfate of Lime has notable applications in the medical field. It is commonly employed in orthopedics to make casts and molds for immobilizing fractured bones during the healing process. Furthermore, it is utilized as a dietary supplement, known as calcium sulfate, to provide a source of dietary calcium.
Overall, Anhydrous Sulfate of Lime is an important compound with diverse applications in multiple industries, ranging from construction to healthcare. Its anhydrous nature lends distinctive properties and functionality for various purposes.
