The dissertation is directed on definition of laws of structurization in samples gazars at their crystallization from two refrigerators located in one form. For the first time key parameters of process for reception of homogeneous porous structure of preparations are revealed at axial orientation of fronts of crystallization, axial-radial, counter, to change of a direction of the form at crystallization of samples. Conditions for destruction of defective zones of the big time which arise in a place of a meeting of fronts gas eutectic crystallization are certain. Sizes of relative heat conductivity gazars and mount its dependence on their porosity have been measured. Reception process gazars by means of an electric arch which has shown formation possibility small porous structures gazars on a surface of monolithic products without special conditions and increase of pressure of crystallization is investigated. Destruction processes gazars, the crack durability and anisotropy of mechanical properties are investigated. For the first time researches on use gazars, as bases for capillary heat and mass conduction materials with different liquids which transfer heat are carried out. Results of researches of heat conductivity gazars are supposed to be introduced at manufacturing of capillary thermal pipes.
