摘要

Abstract—

The thermal conductivity of a series of single crystals of Ca1–x–ySrxNdyF2+y ternary solid solutions containing 0–30 mol % SrF2 and 10–30 mol % NdF3 has been measured in the temperature range 50–300 K by an absolute steady-state axial heat flow technique. An increase in the percentage of strontium and, especially, neodymium in the solid solutions is accompanied by a decrease in their thermal conductivity. The temperature dependence of thermal conductivity for all of the solid solutions studied is characteristic of disordered materials.
