Gypsum is a common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate (CaSO4.2H2O). In well-developed crystals, the mineral commonly has been called selenite. The fibrous massive variety has a silky luster and is called satin spar, and the fine-grained massive variety is called alabaster. Gypsum is a non-metallic mineral that is available in various forms. Due to its wide range of variety, it is considered useful in many fields.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO42H2O. It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard. 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. Mohs scale of mineral hardness, based on scratch hardness comparison, defines hardness value 2 as gypsum. It forms as an evaporite mineral and as a hydration product of anhydrite. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing Process , upon the Cooling of clinker, a small amount of gypsum is introduced during the final grinding Process . Gypsum is added to control the âsetting of cement.
Product description, Product introduction: The main chemical composition of gypsum is CaSO4, mohs hardness is from 3 to 3.5, the density is from 2.9 g/cm3 to 3.1 g/cm3. The fusion of gypsum in acid is greater than water, and is made by crushed gypsum ore. The gypsum used for friction materials in order to improve the coefficient of friction, reduce the cost. Gypsum is used for the disc brake pads and drum brake and clutch. The recommended regular consumption of Basalt is from 2% to 8%. The character of gypsum: Gypsum is most widely distributed mineral in the nature, in a broad sense is containing calcium sulphate (CaSO4) of white mineral. Natural gypsum is divided into two major categories of gypsum and anhydrite according to chemical composition, and can be divided into five kinds of fiber gypsum, gypsum, alabaster, ordinary plaster, earthy plaster according to the shape and structure.In the gypsum mineral deposit in Lingxiang Town Daye city, transparent single crystal gypsum crystal group is found growing in the iron ore deposit cave.Gypsum has the character of good lubrication, solidification, heat acid and alkali resistance, heat insulation and good for oil adsorption, etc..Because of the glittering and translucent white, like baby's blanket long, has the elusive mystery, the single crystal of gypsum prisms surface to the 5cm to 6 cm wide, the elderly can be up to 16 cm, still keep 10cm to 20 cm long inside some crystal gas-liquid inclusions swam back and forth, wonderful and moving!

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral Uses of Gypsum Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in Portland cement. Varieties of gypsum known as satin spar and alabaster are used for a variety of ornamental purposes; however, their low hardness limits their durability.
Gypsum is a very soft sulfate mineral composed of Calcium Sulfate Dehydrate, with the chemical formula CaSO4�·2H2O.It can be used as a fertilizer, as a mineral it is alabaster, which has been used for sculpture by many cultures including Ancient Egypt. It forms as an evaporate mineral and as a hydration product of anhydrite. 50Kg PP Bags or as per our valued customer demand USES OF GYPSUM Fertilizer and soil conditioner A component of Portland cement used to prevent flash setting of concrete Manufacturing plaster of Paris Gypsum board is primarily used as for walls and ceilings, and is known in construction as drywall or plasterboard. Varieties of gypsum known as satin spar and alabaster are used for variety of ornamental purposes, however their low hardness limits their durability Gypsum is added to foot creams, shampoos and hair products (conditioners etc) Gypsum is also used in the medical industry. Typically, the rocks are ground into a fine powder and used for hard casts to set broken bones and sprains. A primary ingredient in toothpaste Origins: Egypt, Iran
Gypsum is a very soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It is found in alabaster. there is other analysis as customer need uses: 1- calcinated gypsum is about 95 % of gypsum uses that we heat the gypsum to 130 degree which remove water and become hemi hydrated gypsum that called plaster of paris, it used in wall plaster, wall lining, plaster board, wall board, tiles for ceikings, partitions. Thermal isolation, regulator to moisture measurements. 2- add Uncalcined gypsum crushed from 3 to 6 % to produce Portland cement so solidification speed become low. 3- gypsum contain 15-20 % sulfur produce ammonium sulfate which act as natural fertilizer. 4- glass industry to easily remove the gases. 5- fine gypsum use in resin industry, paper filler, in soil used in drilling petroleum well. • by heating to 1093 degree, calcium sulfide form which produce sulfuric acid and lime. • A binder in fast-dry tennis court clay. • Plaster of Paris (surgical splints; casting moulds; modeling). • A wood substitute in the ancient world; for example, when wood became scarce due to deforestation on Bronze Age Crete, gypsum was employed in building construction at locations where wood was previously used.[19] • A tofu (soy bean curd) coagulant, making it ultimately a major source of dietary calcium, especially in Asian cultures which traditionally use few dairy products. • Adding hardness to water used for homebrewing. • A component of Portland cement used to prevent flash setting of concrete. • Soil/water potential monitoring (soil moisture tension). • A common ingredient in making mead. • In the medieval period it was mixed, by scribes and illuminators, with lead carbonate (powdered white lead) to make gesso which was applied to illuminated letters and gilded with gold in illuminated manuscripts. • In foot creams, shampoos and many other hair products. • Impression plasters in dentistry
