Ba4 Cr4 F20
semiconductor· Ba4 Cr4 F20
Ba₄Cr₄F₂₀ is a complex barium chromium fluoride ceramic compound belonging to the mixed-metal fluoride family. This material is primarily of research and development interest rather than established industrial production, with potential applications in solid-state ionics, optical devices, and specialized electronic ceramics where fluoride-based frameworks offer unique ionic conductivity or optical transparency. The compound's notable feature is its layered fluoride structure containing both Ba²⁺ and Cr³⁺ cations, making it a candidate for studying fluoride ion conduction mechanisms and for applications requiring chemically stable, corrosion-resistant matrices in advanced functional ceramics.
