HYDROTHERMAL PROCESSES OF CRYSTAL SYNTHESIS, POWDER SYNTHESIS, AND WATER-TREATMENT

The physicochemical foundations and problems for the application of hy drothermal processes for manufacturing monocrystals and finely divided powders, as well as for destroying harmful wastes by the method of su percritical water oxidation, are considered. An analysis is made to sh ow that the most common and pressing tasks are modeling complex equili bria and obtaining reliable experimental data on the properties of hig h-temperature solutions. The recent achievements in the held of thermo dynamic calculations and experimental techniques and investigations fo r hydrothermal systems are briefly reviewed.
