CeF3

Cerium fluoride (CeF₃) is an inorganic ceramic compound belonging to the rare-earth fluoride family, valued for its optical transparency in the ultraviolet and infrared regions. It is primarily used in specialized optical systems, phosphors, and nuclear fuel applications where its chemical stability and radiation resistance are critical; it also serves as a precursor material in rare-earth element processing and as a catalyst in chemical synthesis. Engineers select CeF₃ over alternative fluoride ceramics when UV-visible transparency combined with thermal stability and low solubility in aqueous environments is required, making it particularly relevant for harsh-environment optical components and advanced materials research.
