摘要：
Plutonium dioxide synthesis is an essential step in fuel reprocessing, solution combustion synthesis method (SCS) can offer advantages on fuel preparation. This study reports for the first time the synthesis of PuO2 by SCS with citric acid. It allowed to determine an optimal ratio for citric acid over plutonium ratio (CA/Pu=1.1) for PuO2 synthesis, which is consistent with the propellant chemistry theory, leading to oxides with SCS's characteristic morphologies.
