Ca2FeCuSeO3

Ca₂FeCuSeO₃ is an experimental mixed-metal oxide ceramic compound containing calcium, iron, copper, and selenium. This material belongs to the family of complex metal selenates and oxides under investigation for functional ceramic applications, particularly where multivalent transition metals and rare elemental combinations might provide unique electronic, magnetic, or catalytic properties. Research on such compounds typically targets energy storage, photocatalysis, or solid-state chemistry applications where the interplay between Fe²⁺/Fe³⁺ and Cu²⁺ oxidation states offers tunable performance.
