gypsum | Definition, Uses, & Facts | Britannica

Gypsum, common sulfate mineral of great commercial importance, composed of hydrated calcium sulfate (CaSO 4 ·2H 2 O). In well-developed crystals the mineral commonly has been called selenite. The fibrous massive variety has a silky lustre and is called satin spar; it is translucent and opalescent and is valued for ornaments and jewelry.

Gypsum

Gypsum (calcium sulfate, CaSO 4 ·2H 2 O) is a naturally occurring mineral used in different kinds of industrial application. When heated above 120 °C, a part of the chemically bound water is released and different mineral calcium sulfates like hemihydrate (CaSO 4 ·0.5H 2 O; formed at 130–160 °C) and anhydrite (CaSO 4 ; formed at 290–900 °C) are formed.

Gypsum

 · Gypsum. Pure gypsum is hydrous calcium sulphate (CaSO 4 .2H 2 O). It is a soft mineral, white when pure, but of varying shades of grey, yellow, red or brown if impure. The main use for Victorian gypsum is for agricultural soil conditioning, although demand for this fluctuates in response to the rural economy and climatic conditions.
