In view of a lot of advantages by the co-precipitation method,
such as the uniform material chemical composition, good purity
and good crystal structures and low sintering temperatures, it becomes
the research and development focus of the preparation of
ceramic nuclear fuel and material in the world [11]. As an advanced
technology to produce ceramic materials, however, there are rare
research reports on the preparation of CaO-doped UO2-10 wt%
Gd2O3 fuel pellets by co-precipitation reaction method.
