Gypsum Chime Page University Of Wisconsinmadison

Gypsum is a hydrated calcium sulfate with composition CaSO 4 2H 2 O. It commonly occurs as a chalky powder or occasionally as small crystals. In gypsum, the structure is layered, parallel to the b direction. Tetrahedral SO 4 anions are linked by Ca cations as chains parallel to c, which form as double sheets interlayered with sheets of water molecules.
