· JVASP-110958· YBiO2F2

YBiO2F2 is a rare-earth bismuth oxyfluoride ceramic compound combining yttrium, bismuth, oxygen, and fluorine in a mixed-anion structure. This material belongs to the family of fluoride-containing oxides, which are of significant research interest for optical, thermal, and electrochemical applications where conventional oxides fall short. The incorporation of fluoride ions can enhance ionic conductivity, reduce sintering temperatures, and modify optical transparency compared to pure oxide analogues, making it a candidate material for emerging technologies in solid-state electrolytes, photonic devices, and high-temperature thermal barriers.
