ceramic

· JVASP-30206· Ta3O5F5

Ta3O5F5 is a mixed-valence tantalum oxide fluoride ceramic combining tantalum pentoxide with fluorine substitution, representing a specialized compound in the tantalum oxide family. This material is primarily of research and development interest for advanced functional ceramics applications, where the fluorine dopant can modify ionic conductivity, optical properties, or chemical reactivity compared to standard tantalum oxide. Its use in industrial applications remains limited; potential development areas include solid-state electrolytes, photocatalytic coatings, or specialized refractory components where fluorine incorporation offers performance advantages over conventional tantalum ceramics.
