Chemical structure of gypsum
The structure of gypsum consists of layers of calcium (Ca 2+) and sulfate (SO 2− 4) ions tightly bound together. These layers are bonded by sheets of anion water molecules via weaker hydrogen bonding , which gives the crystal perfect cleavage along the sheets (in the {010} plane). See more Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard See more Gypsum is moderately water-soluble (~2.0–2.5 g/L at 25 °C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures.
