Thermal diffusivity and conductivity of Hg1-xZnxTe solids and melts

The thermal diffusivity of pseudobinary Hg1-xZnxTe solids and melts was measured by the laser flash method. The measured diffusivities for the solids of 0.10 less than or equal to x less than or equal to 0.30 are about 60% of that of the HgTe solid. Those for the melts rise rapidly with temperature but less so with increasing x. For x=0.30, the diffusivity of the melt is about one third of that of the HgTe melt. Using the calculated heat capacity data from the associated solution model and measured density values, the thermal conductivity for the pseudobinary Hg1-xZnxTe solids of 0.10 less than or equal to x less than or equal to 0.30 and for the melts of x = 0.10, 0.16, and 0.30 was determined.
