Description

The microstructure of Gd2O3-UO2 pellets (0∼10 wt%) prepared in different conditions, the homogeneity distribution of Gd2O3 in the pellets and the lattice parameter of solid solution are studied by metalloscope, WDS, EDAX, SEM-image processing system, XRD and image analyzer. The theoretical density has been calculated. The effect of size and content of Gd2O3 particles, the blend process, the sintering temperature and time, and the sintering atmosphere on the microstructure of Gd2O3 pellets and the homogeneity of Gd2O3 in the pellets are studied. (16 refs., 10 figs., 8 tabs.)
