· JVASP-35506· Sr4Bi2O

Sr4Bi2O is an experimental strontium-bismuth oxide ceramic compound belonging to the perovskite-related oxide family. While not yet commercialized at scale, this material is of research interest for applications requiring high-temperature stability and ionic conductivity, particularly in solid-state electrolytes and oxygen-ion conducting membranes. Its notable characteristics within the bismuth-strontium oxide system make it a candidate for next-generation solid oxide fuel cells and gas-separation technologies, where conventional materials face thermal or chemical degradation constraints.
