Critical phenomena in water-salt systems

The experimental data on critical phenomena in water-salt systems are gener alized. In these systems, water plays the role of the more volatile compone nt, and salt solid phases are stable to supercritical temperatures. The cla ssification of the main types of complete phase diagrams, which describe al l phase states of a substance in wide temperature and pressure ranges, is p resented. Apart from an analysis of the experimental data, some theoretical models that are: used to describe high-temperature aqueous solutions of el ectrolytes are considered.
