Abstract
A chemical model is used to examine the phase behaviour of salt mixtures. The principal types of phase changes including crystallization/dissolution, hydration/dehydration and the formation and decomposition of double salts are illustrated for simple mixtures of two salts. The model is successfully applied to predict the crystallization properties of a four-component system. It is shown how several possible sequences of salt deposition and phase transformations are induced by changes of the ambient relative humidity. In addition an X-ray diffraction technique is presented which can be used to study the phase behaviour of salts under controlled conditions of temperature and relative humidity.
