Gypsum - Chemical Formula, Properties, Types, Uses and FAQ

The main components of gypsum are calcium sulfate (CaSO 4) and water (H 2 O). Its chemical name is Calcium Sulphate Dihydrate and the chemical formula of gypsum is represented as CaSO 4.2H 2 O. Gypsum and Anhydrite (CaSO 4) are very similar chemically just that gypsum has 2 water molecules and Anhydrite does not contain any water molecules.

Gypsum - Vasuki Mines Minerals

Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures. Gypsum also crystallizes as translucent crystals of selenite.
