ceramic

· JVASP-41165· Na3UF8

Na3UF8 is a ceramic compound containing sodium and uranium fluorides, representing a halide ceramic within the actinide materials family. This material is primarily of research interest rather than established in high-volume industrial production, with potential applications in nuclear fuel chemistry, uranium processing, and advanced nuclear materials where fluoride-based ceramics offer chemical stability and thermal properties suited to extreme environments. Engineers and materials scientists investigate such uranium fluoride compounds for their role in nuclear fuel cycles and as model systems for understanding actinide chemistry and ceramic behavior under nuclear irradiation.
