Sr3Fe2O6

Sr3Fe2O6 is a strontium iron oxide ceramic compound belonging to the perovskite family, characterized by a mixed-valence iron structure that enables ionic and electronic conduction. This material is primarily investigated for electrochemical applications where oxygen ion transport and catalytic activity are critical, particularly in solid oxide fuel cells (SOFCs), oxygen separation membranes, and electrocatalysis research. Compared to conventional stabilized zirconia or single-phase perovskites, Sr3Fe2O6 offers potential advantages in oxygen permeability and catalytic performance, though it remains largely in the research phase for commercial deployment.
