Abstract

Small kernels of UO2-Gd2O3 were produced from their nitrate solutions by the application of sol-gel process in place of the more conventional process of mixing powders. The sol-gel method consisted of the following steps: sol preparation, sol drop dispersion, gellation, washing of gelled microspheres, aging, drying, calcination, reduction, and sintering.
