<p>Multicomponent metallic oxides, which are particularly suited toward use in fabricating mixed conducting membranes used in processes for producing syngas, are novel non-stoichiometric, A-site rich compositions represented by the formula (LnxCa1-x)yFeO3-δ, wherein Ln is La or a mixture of lanthanides comprising La, 1.0⊃x⊃0.5, 1.1≥y⊃1.0 and δ is a number which renders the metallic oxide charge neutral.</p> |
