<P>PROBLEM TO BE SOLVED: To provide a support for an oxygen separation membrane which has a coefficient of thermal expansion slightly different from that of the oxygen separation membrane and can maintain high oxygen ion conductivity and a method for producing the support. <P>SOLUTION: The support is composed of at least one selected from the group consisting of multiple oxides shown by the formula: La<SB>1-x</SB>Ae<SB>x</SB>MO<SB>3</SB>, stabilized zirconia, and cerium oxide. The average pore diameter r is larger than 0.1 μm and smaller than 20 μm, and the porosity p is in the range between 5% and 60%. The support which can maintain high oxygen ion conductivity can be produced easily and stably by molding and baking a powdered raw material at least 10 μm in an average particle size. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
