摘要：A method of producing a composite oxygen ion membrane and a compositeoxygen ion membrane in which a porous fuel oxidation layer and a dense separation layerand optionally, a porous surface exchange layer are formed on a porous support frommixtures of (Ln1-xAx)wCr1-yByO3-δ and a doped zirconia. In the porous fuel oxidationlayer and the optional porous surface exchange layer, A is Calcium and in the denseseparation layer A is not Calcium and, preferably is Strontium. Preferred materials are(La0.8Ca0.2)0.95Cr0.5Mn0.5O3-δ for the porous fuel oxidation and optional poroussurface exchange layers and (La0.8Sr0.2)0.95Cr0.5Fe0.5O3-δ for the dense separationlayer. The use of such materials allows the membrane to sintered in air and without theuse of pore formers to reduce membrane manufacturing costs. The use of materials, asdescribed herein, for forming the porous layers have application for forming any type ofporous structure, such as a catalyst support.
