Thermal expansion of ZrC, which has the NaCI type structure, was determined from, 120 to 300 K by a powder X‐ray diffraction method. The lattice parameter was measured precisely using a specially designed D‐shaped symmetrical back‐reflection‐focusing camera with the specimen hanging from a cryoflask in the vacuum chamber outside the camera on the Rowland circle. The average coefficient of linear thermal expansion of ZrC in this temperature range is 6.22 x 10 ‐6 /K. The Zr/C ratio was 0.993.
