· JVASP-52219· U3O5

U3O5 is a mixed-valence uranium oxide ceramic compound that exists in the intermediate oxidation state between UO2 and U3O8. It is primarily of interest in nuclear fuel chemistry and materials research, where it represents a potential intermediate phase in the oxidation of uranium dioxide fuel under specific thermal and atmospheric conditions. This material is significant in nuclear engineering contexts for understanding fuel degradation mechanisms, storage stability, and potential reprocessing scenarios, though it is not commonly employed as a primary engineered component in commercial applications.
