Gypsum Calcination. Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120 ...
Gypsum deposits occur in many countries, but Spain, Thailand, the United States, Turkey, and Russia are among the leading producers. The largest gypsum crystal was found in the Braden mine in Chile and exceeds 3 metres (about 10 feet) in length and metre (about feet) in diameter. In the, commercial sedimentary gypsum deposits occur in New York and Michigan; others of economic ...

The capabilities of gypsum as a building material depends to a great extent on the chemical composition of the raw material. To ensure targeted, highquality processing into gypsum plaster, plasterboard or gypsum blocks, you need technology solutions that process natural or synthetic gypsum into stucco or highfired plaster.
Gypsum is a sedimentary rock and a crystalline mineral. "Gypsum is a soft, white to gray, "chalky" mineral composed of calcium sulfate and water," says Raymond Anderson of Iowa's Department of Natural Resources. Gypsum's chemical symbol is CaSO4•2H2O.

Although gypsum plaster is easy to apply and requires less experienced manpower as compared to the traditional cement mortar, it is important to properly prepare the wall surface and properly apply gypsum plaster to ensure no cracks, peel offs etc., In this article, we discuss in detail the procedure to apply gypsum plaster on wall properly.
Gypsum, common sulfate mineral of superb industrial significance, composed of hydrated calcium sulfate (CaSO4 ·2H2O). In properlydeveloped crystals the mineral normally has been called selenite. The fibrous large variety has a silky lustre and is known as satin spar; it is translucent and opalescent and is valued for ornaments and jewellery.
preheating process. Initially, it was heated at 170oC with a rate of oC/min and held at this temperature for 3 hours. Then the temperature was increased to 750 oC with a rate of oC/min and held at this temperature for 5 hours. At this stage, burnout process was expected to occur in order to ensure that all the wax
