· JVASP-11572· BiF4

BiF₄ is an ionic ceramic compound composed of bismuth and fluoride, belonging to the family of metal fluorides used in specialized optical, electrochemical, and thermal applications. BiF₄ is primarily investigated in research contexts as a fast-ion conductor and fluoride-based electrolyte material, with potential applications in solid-state batteries, thermal barrier coatings, and high-temperature devices where bismuth fluorides offer unique ionic conductivity and chemical stability. Its dense crystalline structure and fluoride composition make it notable for environments requiring resistance to corrosive conditions and high thermal stability, though it remains less established in mainstream industrial use compared to other fluoride ceramics.
