· JVASP-44794· Na2FeAsCO7

Na₂FeAsCO₇ is an iron-based mixed-valence ceramic compound containing arsenic and carbonate functional groups, belonging to the class of transition metal oxysalt ceramics. This material is primarily of research and academic interest rather than established industrial production, with potential applications in advanced ceramics, solid-state chemistry, and materials science exploring novel iron-arsenic coordination frameworks. Its notable features include the combination of iron redox chemistry with arsenic coordination, making it relevant to researchers investigating unusual ceramic phases for potential uses in catalysis, ion exchange, or specialized refractory applications where arsenic-containing ceramics may offer unique properties unavailable in conventional oxide systems.
