Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly.
Furthermore, increased use of synthetic gypsum conserves natural gypsum and reduces the need to mine finite resources. Synthetic gypsum products even have benefits over natural gypsum products in terms of costs and environmental impacts. THE GYPSUM PROCESSING HANDBOOK | 4 1.
