· Ta5 O5 F15

Ta₅O₅F₁₅ is a tantalum oxide fluoride compound belonging to the semiconductor class, combining tantalum pentoxide with fluorine substitution to modify electronic and chemical properties. This material is primarily of research and developmental interest for applications requiring halogenated oxide semiconductors, particularly in fluoride-based systems where enhanced chemical stability, modified band gap, or improved ionic conductivity is desired compared to conventional tantalum oxides. The fluorine incorporation makes this compound notable for potential use in solid-state electrolytes, advanced dielectrics, and photonic devices where the unique combination of tantalum's high dielectric strength and fluorine's chemical inertness can be leveraged.
