The thermal expansion of a number of cubic refractory compounds of thorium was measured by high‐temperature X‐ray diffraction. The coefficients of thermal expansion range from 7.5 to 8.2 × 10 −6 /°C for ThN, ThC 0.84 , ThP 0.71 , ThP 0.61 , and Th 3 P 4 between 900° and 1300°, 1450°, 1750°, 1750°, and 1150°, respectively; the coefficients for ThS, ThB 6 , and ThO 2 are in the range of 11.2 to 12.0 × 10 −6 /°C between 900° and 1400°, 1700°, and 2100°, respectively. The results are discussed in relation to other properties of these compounds.
