The dehydration of gypsum (CaSO 4 β’ 2H 2 O) into calcium sulfate hemihydrate (CaSO 4 β’ 0.5H 2 O) and anhydrites ( -CaSO 4 and -CaSO 4 ) was carried out by heating under a constant pressure of water vapor using Controlled transformation Rate Thermal Analysis. No intermediate formation of calcium sulf
