英文摘要Several samples of (U1-xNdx)(3)O-8 with different Nd content were prepared by different process. After high temperature oxidation, the final oxidized products were found to be a mixture of small particles Nd-rich (U1-yNdy)O2+v phases and large particles Nd-poor (U1-zNdz)(3)O8-w phases by XRD and SEM analysis. This study indicated that (U1-xNdx)(3)O-8 powder formed a solid solution firstly at 1100 degrees C or high. The recrystallization of this solid solution happened and the RE-rich fluorite phase formed concurrently when the temperature began to decrease. The present work will provide more information to understand the oxidation behavior of rare-earth doped U3O8 phase at high temperature.
