Gypsum Wikipedia

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.

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. Gypsum is the most common sulfate mineral.

Gypsum White Sands National Park U.S. National Park Service

Gypsum is a hydrous, soft sulfate mineral, specifically a calcium sulfate dihydrate, which means it has two molecules of water in its chemical composition. This is seen in its chemical formula is CaSO 4 2H 2 0. When gypsum is heated and the water within the mineral is evaporated out, gypsum turns into a chalk or plaster, known as plaster of Paris.

Gypsum Chemical Formula, Properties, Types, Uses and FAQ

The main components of gypsum are calcium sulfate CaSO 4 and water H 2 O . Its chemical name is Calcium Sulphate Dihydrate and the chemical formula of gypsum is represented as CaSO 4.2H 2 O. Gypsum and Anhydrite CaSO 4 are very similar chemically just that gypsum has 2 water molecules and Anhydrite does not contain any water molecules.

Gypsum is calcium sulfate CaSO4 . Refined gypsum in the anhydrite form no water is 29.4 percent calcium Ca and 23.5 percent sulfur S . Usually, gypsum has water associated in the molecular structure CaSO42H2O and is approximately 23.3 percent Ca and 18.5 percent S plaster of paris .

Drywall Wikipedia

Drywall is made primarily from gypsum CaSO 4 2H 2 O . As its chemical formula shows, gypsum contains chemically combined water approximately 50 by volume . When gypsum panels are exposed to fire, heat is absorbed as a portion of the combined water is driven off as steam. This chemical process is called calcination.

Gypsum Wallboard Chemical Additives

Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needlelike gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
