| Abstract: | Solubility measurements have been used to establish the gypsum-anhydrite equilibrium in the CaSO4-H2O system at atmospheric pressure. The saturation equilibrium has been approached both from undersaturated and supersaturated solutions. The invariant point temperature has been found to be 49.5 ± 2.5°C. |
