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, selenite: The mineral gypsum information and pictures

Gypsum has the same chemical composition as the mineral Anhydrite, but contains water in its structure, which Anhydrite lacks. Many Anhydrite specimens absorb water, transforming into the more common Gypsum. Some Gypsum specimens show evidence of this, containing growths of crumpling layers that testify to their expansion from the addition of water.

Raw Gypsum is calcium sulfate dihydrate ((Ca (SO 4) 2H 2 O), also known as gypsum dihydrate, gypsum or gypsum, composition CaO (32.6%), SO 3 (46.5%), H2O+ (20.9%), monoclinic system, crystal is plate-like, usually dense block or fiber, white or gray, red, brown, vitreous or silky luster, Mohs hardness is 2, density 2.3g/cm3.

Properties and Uses of Gypsum - Science Struck

Gypsum is made up of oxygen, calcium, sulfur, and water, and its chemical formula is CaSO 4 ·2H 2 O. Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins. Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins.
