Gypsum powder Jonoub Gypsum
Gypsum powder (hydrous calcium sulfate/calcium dehydrate or CaSO4-2H2O) is a white, smooth powder that is derived from heating gypsum rock. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, (often called "plaster") and, if heated further, to anhydrous calcium sulfate (anhydrite).Gypsum Wikipedia,A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Gypsum also crystallizes as translucent crystals of selenite.
gypsum Definition, Uses, & Facts Britannica
Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate (CaSO 4 ·2H 2 O). In well-developed crystals the mineral commonly has been called selenite. The fibrous massive variety has a silky lustre and is called satin spar; it is translucent and opalescent and is valued for ornaments and jewelry.Gypsum Mineral Uses and Properties,Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water.
