Abstract
The thermal expansion of cubic pyrochlore Ce2Zr2O7 has been measured from room temperature to 898 K on polycrystalline material in conjunction with structural analyses using neutron diffraction. This compound has a thermal expansion coefficient in line with the other comparable lanthanoide pyrochlore oxides. The coefficient can be expressed as alpha(T) = 8.418 x 10(-6) + 0.9861 x 10(-9) x T. The structural refinements performed for each measured temperature showed a comparable linear evolution of the Ce-O/Zr-O distances (within 0.57%).
