· Na2FeO2

Sodium iron oxide (Na2FeO2) is an inorganic ceramic compound combining sodium and iron oxides, belonging to the family of mixed metal oxides. While not a widely established commercial material, it appears primarily in research contexts exploring iron oxide systems for catalytic, electrochemical, or structural applications. Engineers considering this compound would typically be investigating novel catalyst formulations, battery or fuel cell components, or specialized ceramics where the combined properties of sodium and iron oxides offer advantages over single-phase alternatives.
