· Na12 Fe4 O12

Na₁₂Fe₄O₁₂ is a mixed-valence iron oxide compound with a complex crystal structure containing both sodium and iron cations, classified as a semiconductor ceramic. This material belongs to the family of iron-sodium oxides and is primarily of research interest for energy storage and electrochemical applications, where its mixed oxidation states and ionic conductivity make it a candidate for battery cathodes, solid electrolytes, or catalytic supports. While not yet widely commercialized in mainstream engineering applications, compounds in this structural family show promise for next-generation solid-state battery systems and oxygen reduction catalysis due to their tunable electronic properties and potential for ion transport.
