· Sr3Fe2O5

Sr3Fe2O5 is an oxide ceramic compound belonging to the perovskite-related family, composed of strontium, iron, and oxygen in a layered crystalline structure. This material is primarily investigated in research contexts for electrochemical and catalytic applications, particularly in solid oxide fuel cells (SOFCs) and oxygen permeation membranes, where its mixed ionic-electronic conductivity and redox activity are leveraged. While not yet widely commercialized, Sr3Fe2O5 represents the class of strontium iron oxides that show promise as cathode materials and oxygen transport membranes due to their thermal stability and catalytic properties relative to conventional alternatives.
