WHAT IS GYPSUM Gypmak

By heating of gypsum found in nature (CaSO4+2H2O) to 150 to 160°C,1,5 mol water evaporates of 2 moles in the chemical structure and it is changed as CaSO4+1/2H2O called calcination process. 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.
