· JVASP-51619· Rb4Fe2O5

Rb₄Fe₂O₅ is an iron-based mixed-valence oxide ceramic compound containing rubidium, belonging to the family of complex metal oxides with potential electrochemical or magnetic functionality. This material is primarily of research interest rather than established industrial use, studied for its structural and electronic properties as part of fundamental materials science investigations into rubidium–iron–oxygen systems. The compound may be explored for advanced applications in solid-state chemistry, catalysis, or functional ceramics where the mixed oxidation states of iron and the presence of alkali metal cations could provide useful electrochemical or thermal properties.
