· JVASP-101263· WO2F2

WO2F2 is a tungsten oxide fluoride ceramic compound combining tungsten, oxygen, and fluorine elements into a mixed-anion ceramic structure. This material belongs to the family of fluoride-containing oxides and is primarily investigated in research contexts for its potential in advanced ceramics, solid-state chemistry, and functional materials applications. Its mixed ionic-covalent bonding character and dense crystal structure make it of interest for studies in high-temperature stability, ionic conductivity, and catalytic support materials, though industrial-scale applications remain limited compared to conventional tungsten oxides or fluorides.
