Abstract

The thermal conductivity of a series of single crystals of Ca1–xySrxNdyF2+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.

Ca1-x-ySrxNdyF2 +y固溶体单晶的导热性
用绝对稳态轴向热流技术测定了含0-30 mol % SrF2和10-30 mol % NdF3的Ca1-x-ySrxNdyF2 +y三元固溶体单晶在50-300 K温度范围内的热导率。锶,特别是钕在固溶体中所占比例的增加,伴随着它们的导热性的降低。所研究的所有固溶体的热导率的温度依赖性是无序材料的特征。

期刊介绍: Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
