Calcium sulfate hemihydrate
Calcium sulfate hemihydrate (CAS: 10034-76-1) is a hydrated form of calcium sulfate, commonly known as plaster of Paris. Its chemical formula is CaSO₄·0.5H₂O, with a molecular weight of 145.15 g/mol. This inorganic salt is a white crystalline powder extensively used in construction for its setting properties, in medicine for casting broken bones, and as a precursor in various chemical syntheses.
Construction and Building Materials
Utilised in the production of plasterboard, stucco, and decorative mouldings due to its ability to harden when mixed with water.
Medical Applications
Forms the basis of plaster casts for immobilising fractured limbs, offering a rigid yet lightweight support during healing.
Chemical Synthesis
Serves as a reagent or precursor in the synthesis of other calcium compounds and inorganic chemicals.
Industrial Uses
Can be employed as a drying agent, a filler in plastics and paints, and in the manufacturing of certain types of paper.
