FeO₂ is an iron oxide ceramic compound representing a higher oxidation state of iron than common magnetite or hematite phases. This material is primarily of research and experimental interest rather than established industrial production, studied for its potential in catalysis, energy storage, and advanced oxidation applications where iron's variable oxidation chemistry offers functional advantages. Engineers would consider FeO₂ when conventional iron oxides are insufficient for high-oxidation-state requirements, though availability, phase stability, and scalability remain significant practical constraints compared to established iron oxide ceramics.
