· Sr3 Mn4 O12

Sr₃Mn₄O₁₂ is a mixed-valence manganese oxide ceramic with a layered perovskite-related crystal structure, belonging to the family of strontium manganates. This material is primarily investigated in research contexts for its potential as a cathode material in solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs), where its mixed ionic-electronic conductivity and catalytic properties for oxygen reduction are of interest. Sr₃Mn₄O₁₂ offers potential advantages over traditional perovskite cathodes in terms of phase stability and oxygen transport kinetics, making it a candidate for next-generation electrochemical energy devices operating at intermediate to high temperatures.
