· JVASP-7869· Sr2MnO4

Sr2MnO4 is a layered perovskite ceramic compound composed of strontium, manganese, and oxygen, belonging to the family of mixed-valence transition metal oxides. This material is primarily investigated in research contexts for electrochemical and magnetic applications, particularly as a potential cathode material for solid oxide fuel cells (SOFCs) and as a candidate for oxygen transport membranes due to its ionic and electronic conductivity. Sr2MnO4 represents an important structural class in materials science for high-temperature energy conversion devices, where the layered crystal structure and manganese redox chemistry enable superior performance compared to conventional ceramic electrolytes and cathodes.
