· NaBiF6

NaBiF6 (sodium bismuth fluoride) is an inorganic ceramic compound belonging to the fluoride family, composed of sodium, bismuth, and fluorine ions in a crystalline structure. This material is primarily of research and specialized industrial interest, used in optical applications, fluoride-based solid electrolytes for advanced batteries, and as a precursor in synthesis of bismuth-containing functional ceramics. NaBiF6 is notable for its high density and thermal stability, making it attractive for next-generation energy storage systems and photonic applications where bismuth-based oxyfluorides show promise, though it remains less established than alternative fluoride ceramics in production-scale engineering.
