The lattice spacings of the intermetallic compound Ni3Zr have been measured by X-ray methods in the temperature interval 298–1033 K using a Debye–Scherrer camera. In all the cases the measured lattice spacings have been found to increase non-linearly with temperature and the dependence has been expressed by a polynomial of second degree from the least-squares fitting of the data. The thermal expansion coefficients for both parameters have been found to decrease with increase in temperature.
