· JVASP-26420· YBi2BrO4

YBi2BrO4 is an yttrium-bismuth bromide oxide ceramic compound, a mixed halide-oxide material that represents an emerging class of hybrid ionic ceramics. While not yet commercialized at scale, this material family is under active research for applications requiring combinations of ionic conductivity and thermal stability that differ from conventional oxide ceramics. Its layered crystal structure and bismuth content make it a candidate for solid electrolyte and photocatalytic research, though engineering adoption remains limited to laboratory and prototype development contexts.
