· JVASP-52321· Nb3O7F

Nb3O7F is a niobium oxide fluoride ceramic compound combining niobium oxide with fluorine, belonging to the family of mixed-anion ceramics. This material is primarily investigated in research contexts for applications requiring high thermal stability, chemical resistance, and specialized electronic or ionic conducting properties that distinguish it from conventional oxide ceramics. Industrial adoption remains limited, with potential relevance emerging in advanced electrochemical devices, solid-state electrolytes, and specialized refractories where fluorine-doping of niobium oxides offers performance advantages.
