The thermal expansion characteristics of polycrystalline delta (face- centered-cubic) zirconium hydride and epsilon (body-centered-tetragonal) zirconium hydride were determined between room temperature and 362 and 300 deg C. respectively, by means of x-ray diffraction techniques. The average linear thermal expansion coefficient for the delta phase is 2.98 x 10/sup -6// deg C for the range 24 to 362 deg C. For the epsilon phase, the average coefficients for the range 24 to 300 deg C are -1.4 x 10/sup -6// deg C and 30.6 x 10/sup -6// C for the a and c directions. respectively, and 9.3 x 10/sup -6// deg C for the randomly oriented polycrystalline material.
