The hemihydrate (CaSO 4 Â·~0.5H 2 O or (CaSO 4) 2 Â·H 2 O) is better known as plaster of Paris, while the dihydrate (CaSO 4 Â·2H 2 O) occurs naturally as gypsum.he anhydrous form occurs naturally as Î²-anhydrite. Depending on the method of calcination of calcium sulfate dihydrate, specific hemihydrates are sometimes distinguished: alpha-hemihydrate and beta-hemihydrate.
hemihydrate, n a chemical compound in which the number of water molecules is half that of the other portion of the compound. In dentistry, hemihydrates are used in the manufacture of crowns, inlays, bridges, and dental molds. chemical compound with one molecule of water for every two molecules of the other substance. In dentistry, calcium sulfate hemihydrate is mixed with water to produce a hardened plaster or stone (calcium sulfate dihydrate), which, in turn, is commonly used to produce dental models.
