Gypsum - an overview | ScienceDirect Topics

Gypsum molds are made by pouring a plaster–water slurry into a case mold having the same shape as the finally desired greenware. Case molds can be made of gypsum, wood, or plastic. After filling the case mold, the slurry sets into a rigid shape by the chemical hydration of plaster (CaSO 4 · 1 2 H 2 O) to gypsum (CaSO 2 ·2H 2 O).

Gypsum - an overview | ScienceDirect Topics

G. Cressey, in Encyclopedia of Geology, 2005. Introduction. Gypsum (CaSO 4 · 2H 2 O), the most common of the sulphate minerals, is also known as alabaster (a fine-grained massive form), satin spar (a fibrous variety of gypsum), or selenite (colourless transparent gypsum crystals). Gypsum is often found in considerable thicknesses within evaporite sequences and in association with limestones ...

Gypsum - Wikipedia

Gypsum occurs in nature as flattened and often twinned crystals, and transparent, cleavable masses called selenite.Selenite contains no significant selenium; rather, both substances were named for the ancient Greek word for the Moon.. Selenite may also occur in a silky, fibrous form, in which case it is commonly called "satin spar".

Gypsum - an overview | ScienceDirect Topics

Gypsum boards or plasterboards are typical materials used to build light walls. The production process is based on gypsum hydration technology. At the very beginning of the process dehydrated calcium sulfate (gypsum) is converted into CaSO 4 ·0.5H 2 O by heating. Once dehydrated, gypsum is mixed with water, starch, a foaming agent, and other additives.

1. GYPSIFEROUS SOILS IN THE WORLD

1.1 Introduction. Gypsiferous soils are soils that contain sufficient quantities of gypsum (calcium sulphate) to interfere with plant growth. Soils with gypsum of pedogenic origin are found in regions with ustic, xeric and aridic moisture regimes (Nettleton et al. 1982). They are well represented in dry areas where sources for the calcium sulphate exist.
