· JVASP-11746· Na4FeO4

Sodium ferrate (Na₄FeO₄) is an inorganic ceramic compound containing iron in a high oxidation state, primarily of research and specialized industrial interest rather than conventional structural applications. It is investigated for water treatment and purification applications due to its strong oxidizing properties, where it simultaneously acts as a disinfectant and coagulant, offering an alternative to traditional chemical treatments. Its use remains largely experimental and niche compared to conventional ceramics, with potential development in environmental remediation, though industrial adoption has been limited by cost and handling considerations.
