Gypsum Powder Heating Temparture

gypsum powder heating temparture - Strzelnica …

As explained the heating up of gypsum products results in heating up of water crystals present in the gypsum material. This dehydration of gypsum by heat is called as calcination. The calcination results in a covering over the materials that stop it to undergo combustion and allow the material near them to maintain a lower safer temperature.

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.
