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.

What is Gypsum – eurogypsum

From Mines to Mars. Gypsum is a common mineral. It is found in layers that were formed under salt water millions of years ago. When water evaporated, it left the mineral behind. Gypsum is mined from sedimentary rock formations around the world. It takes the form of crystals which can at times be found projecting from rock – leading to its old English name of the Spear Stone. The largest ...
