METAL OXIDE, OXYGEN PERMEABLE MEMBRANE, AND OXYGEN SEPARATION DEVICE
To provide: a complex oxide which, while having a thermal expansion coefficient restricted to a practically trouble-free extent, exhibits a high oxygen permeation rate at lower temperature; and an oxygen permeable membrane and an oxygen separation device using the same.SOLUTION: A complex oxide is represented by the following formula (a): Ba(4-p)CaqFe(3-r)MsO(9+t) (a). In the formula (a), M represents a transition metal element except Fe and at least one or more elements selected from the group consisting of divalent or trivalent transition metal elements are included, p, q, r, and s satisfy the following formulae (p1) to (x1), and t satisfies the following formula (t1). -1≤p≤1 (p1), 0
【課題】熱膨張率が実用上支障のない程度に抑えられながら、より低温で高い酸素透過速度を示す複合酸化物とこれを用いた酸素透過膜及び酸素分離装置を提供する。【解決手段】下記式(a)で表される金属酸化物。Ba(4-p)CaqFe(3-r)MsO(9+t)…(a)但し、上記式(a)において、MはFeを除く遷移金属元素を表し、少なくとも2価又は3価である遷移金属元素からなる群より選択される1種以上の元素を含み、p、q、r、sは下記式(p1)~(x1)を満たし、tは下記式(t1)を満たす。-1≦p≦1(p1)、0<q≦2(q1)、-1<r≦1.5(r1)、0<s≦1.5(s1)、0≦p+q+r+s≦4(x1)、-1≦t≦4(t1)。【選択図】なし
