Abstract:
Ru-doped UO2 materials were synthesized via a sol–gel method and the resulting compounds were subjected to an oxidative heat treatment at 1000 °C. Both as-synthesized and oxidized materials were characterized coupling microscopy, diffraction and spectroscopic techniques. A detailed structural description of the studied compounds is provided. The oxidation of UO2 to U3O8 is complete within the investigated atmosphere and Ru is oxidized to volatile oxide forms.
