• 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 Mineral Uses and Properties

    Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
