The subject of investigation is radiation-convective heat exchange processes at crystal growth installations and heat regime control methods in the installations; highly dispersed liophobic systems consisting of two main components - liquid and capillary-porous medium nonwetting by the fluid. The techniques of simplified consideration of radiation and convective heat exchange components at crystal growth numerical simulation are designed. The techniques are to be used for the growth process real-time control. The methodology of carbonate impurities consideration at cesium iodide crystal growth through modification of crystal and melt absorption coefficient are developed. The algorithm of dynamically rebuilt crystallization interface depending on current temperature conditions is developed. The algorithm provides tracing of the interface position and shape. The low-temperature research unit for highly-dispersed lyophobic system compression-expansion isotherms is produced. The HDLS low-temperature compression-expansion P-V diagram technique is worked out. The new liquid and capillary-porous components for new low-temperature heterogeneous working media are synthesized. The HDLS low-temperature compression-expansion isotherms are received. The analysis is done and the recommendations for low-temperature heterogeneous working media are produced.
