· Ca5B3O9F

Ca₅B₃O₉F is a calcium borate fluoride ceramic compound belonging to the borate ceramic family. This material combines the structural rigidity of borate glass-ceramics with fluoride incorporation, potentially offering improved thermal stability and chemical resistance compared to conventional borosilicate glasses. While primarily investigated in research contexts, materials in this composition family are of interest for specialized applications requiring high-temperature stability, low thermal expansion, or corrosion resistance in aggressive environments.
