Using a simple geometric model, the conditions of equilibrium for topotactical dehydration of gypsum to the hemihydrate in liquid H 2 O were determined. The calculated equilibrium temperature agrees with the experimentally determined temperature at which the rate of topotactical dehydration of gypsum single crystals approaches zero.
