The dehydration of gypsum (CaSO 4 โข 2H 2 O) into calcium sulfate hemihydrate (CaSO 4 โข 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
Bassanite (CaS04 "1 H20) and anhydrite (GAS04) are the low-temperature products of gypsum (CaS04-2H20) dehydration, which are obtained at about 373 and 433 K, respectively. These sulphates have non-centrosymmetric crystallographic point groups, but dielectric measurements do not reveal any piezo-or
