Abstract:

The phase equilibria and phase diagrams of salt-water systems constitute the theoretical basis for chemical industry of inorganic salts. The fundamental studies on the phase equilibrium can provide firm support for the comprehensive development and utilization of salt lake salt resources. In this paper, the recent domestic and international research advances and methods on phase equilibria of slat-water systems from both experimental and theoretical perspectives are summarized. In particular, the experimental methods on the determination of phase diagrams for stable and metastable phase equilibrium systems as well as the factors which cause the change of phase interval and solid crystal type are presented. In addition, based on the up-to-date theoretical methods including thermodynamic models, statistical mechanics theories and computer simulations, the outline of their principles, current situations and possible extensions toward the investigation of stable and metastable phase equilibrium systems are introduced. Finally, the research hotspots in this domain are discussed along with the expectations on the future development.
