· JVASP-42838· Na4MnO4

Sodium manganate (Na₄MnO₄) is an inorganic ceramic compound containing manganese in the +6 oxidation state, belonging to the family of alkali metal manganates. While primarily of research interest rather than established commercial use, this material is investigated in contexts requiring manganese oxides with specific oxidation states, including energy storage systems, catalytic applications, and advanced ceramic formulations where manganese's redox chemistry is exploited.
