Thermal Conductivity of Cubic ZrO2 Single Crystals Stabilized with Yttrium Oxide

The temperature dependence of the thermal conductivity of cubic ZrO2 single crystals stabilized with yttrium oxide from 8 to 40 mol % has been studied in the temperature range 50–300 K. The dependence is analyzed taking into account the phase compositions, the features of the local structures and the electrophysical characteristics of these single crystals.
