利用X射线衍射技术测定了多晶〈UN〉、〈UO2〉、〈UO2·ThO2〉固溶体和〈ThO2〉在室温到约1000°C之间的热膨胀特性。在26°至1000°C范围内，平均线性热膨胀系数（ᾱ×106/∘C）值分别为8.61、10.52、10.18和9.32。将观测到的<UO2·ThO2>晶格常数与E-an Zen方法计算出的晶格常数进行比较表明，随着温度的升高，固溶体变得不太理想。
The thermal expansion characteristics of polycrystalline 〈UN〉, 〈UO2〉, 〈UO2·ThO2〉 solid solution, and 〈ThO2〉 were determined between room temperature and ca 1000°C by means of x‐ray diffraction techniques. For the range 26° to 1000°C, the values of the average linear thermal expansion coefficients (ᾱ×106/∘C) are 8.61, 10.52, 10.18, and 9.32, respectively. A comparison of the observed 〈UO2·ThO2〉 lattice constants with those calculated by the method of E—an Zen indicates that the solid solution becomes less ideal as the temperature increases.
