  • 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). Stucco is applied wet and hardens to a very dense solid.
