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.
The limiting factors for a more extensive use by the Gypsum industry are rest impurities, deviant crystal shape of the Gypsum and quality fluctuations, which can lead to a behaviour not compatible with Gypsum processing, and the higher level of natural radioactivity, depending
