摘要：

The thermal conductivity of single crystals of the solid solution of yttrium fluoride in calcium fluoride Ca1-xYxF2+x with the fluorite structure (x <= 0.20) and the Ca0.27Y0.73F2.73 phase with the tisonite structure has been studied by the absolute steady-state longitudinal heat flow method in the temperature range 50300 K. It has been established that the thermal conductivity drops sharply with increasing yttrium trifluoride concentration, especially in the low-temperature region.
