Na2FeO4

Sodium ferrate (Na₂FeO₄) is an inorganic ceramic compound containing iron in the +6 oxidation state, representing an advanced oxidizing ceramic material with potential applications in water treatment and environmental remediation. Industrial use is primarily driven by its strong oxidizing properties in aqueous solution, where it functions as a disinfectant and coagulant for drinking water and wastewater treatment, offering the advantage of decomposing into benign iron(III) hydroxide rather than persistent chemical byproducts. While not yet mainstream in structural engineering applications, Na₂FeO₄ is of research interest in environmental engineering and materials science as a multifunctional treatment agent, with ongoing investigation into synthesis stabilization and cost-effective production methods to expand its commercial viability.
