La10Mn9O30

La₁₀Mn₉O₃₀ is a mixed-valence lanthanum manganite ceramic compound belonging to the perovskite-related oxide family, synthesized primarily for research and functional applications requiring controlled oxygen stoichiometry and ionic conductivity. This material is investigated for electrochemical and catalytic applications where lanthanum manganites are known to exhibit ion transport, oxygen vacancy dynamics, and redox activity; it represents a specific compositional variant within the broader La-Mn-O system explored for solid oxide fuel cells, oxygen permeation membranes, and catalytic oxidation processes. The layered oxygen coordination and mixed-valence manganese sites distinguish it from simpler perovskites, making it of interest in materials screening for high-temperature oxygen transport and electrochemical stability.
