Features of heat conductivity of polycrystalline zinc sulfide
The results of the experimental studies at range 4 - 400 K of thermal conductivity of ZnS polycrystals with different technological prehistory are presented in the paper. It is established that the magnitude and temperature dependence of polycrystals thermal conductivity depend strongly on their microstructure, due to the method of obtaining. In the microcrystalline samples ZnS, obtained by recrystallization pressing, there is a significant thermal conductivity decrease compared with the single crystal. In the textured samples obtained by deposition from the vapor phase, observed an anisotropy of thermal conductivity relative to the direction of crystal growth.
