WHAT IS GYPSUM

Gypsum loses mass of around 15% during calcination, i.e. if 1000 kg of gypsum plaster is calcined, approximately 850 kg plaster remains, and 150 kg of water vapor is emitted from the chimney. Gypsum found steady work in nature, becomes an unstable structure after calcination.Get price

Calcination

Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.Get price
