La20Cu9O40
ceramic· La20Cu9O40
La₂₀Cu₉O₄₀ is a mixed-valence lanthanum-copper oxide ceramic compound belonging to the family of rare-earth perovskites and layered oxide systems. This material is primarily a research compound of interest for its potential mixed ionic-electronic conductivity and catalytic properties, rather than a widely commercialized engineering material. Potential applications include oxygen separation membranes, catalytic supports for hydrocarbon oxidation, and solid-state electrochemistry devices, where the combination of lanthanum's rare-earth character and copper's variable oxidation states may enable superior performance compared to conventional ceramics.
