· JVASP-57524· UOF4

UOF4 is a uranium oxyfluoride ceramic compound belonging to the halide-oxide ceramic family. This material is primarily of research and specialized nuclear fuel cycle interest, used in uranium processing and conversion applications where fluoride chemistry and oxidation resistance are required. Its selection over alternative uranium compounds is driven by specific chemical compatibility requirements in fluorination processes and intermediate fuel form handling.
