Bi2Sr2Co2O8

Bi₂Sr₂Co₂O₈ is a layered perovskite ceramic compound belonging to the Aurivillius family of oxide materials, characterized by alternating layers of perovskite and bismuth oxide blocks. This material is primarily of research interest for high-temperature thermoelectric and superconducting applications, as the Co-based layered structure can exhibit metallic or mixed-valence behavior depending on preparation and doping conditions. Engineers and materials scientists investigate this compound family for potential use in advanced energy conversion systems where thermal properties and electrical behavior must be optimized at elevated temperatures.
