Uranium trioxide (UO₃) is a ceramic oxide compound of uranium, primarily encountered in nuclear fuel processing and materials science research contexts. Its principal industrial use is as an intermediate in uranium fuel fabrication, where it serves in the conversion and enrichment stages of the nuclear fuel cycle. Engineers and nuclear specialists select UO₃ for its role in controlled nuclear applications, though its handling is restricted to licensed facilities due to radiation and chemical toxicity—making it relevant only in specialized nuclear engineering, weapons-grade fuel production, and advanced ceramics research.
