Title (EN) MELILITE COMPOSITE OXIDE
(FR) OXYDE COMPOSITE DE MÉLILITE
(JA) メリライト型複合酸化物
Abstract:
(EN) Provided is a novel compound which can be used for a positive-electrode catalyst of a metal-air battery. The melilite composite oxide according to the present invention is represented by general formula (BazSr1-z)2CoxFe2-2x(SiyGe1-y)1+xO7 (in the formula, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, and 0 ≤ z ≤ 1, excluding the case where x = 1, y = 1, and z = 0, the case where x = 1, y = 1, and z = 1, the case where x = 1, y = 0, and z = 0, the case where x = 1, y = 0, and z = 1, the case where x = 0, y = 0, and z = 0, and the case where x = 0, y = 0, and z = 1).
(FR) L'invention concerne un nouveau composé qui peut être utilisé pour un catalyseur d'électrode positive d'une batterie métal-air. L'oxyde composite de mélilite selon la présente invention est représenté par la formule générale (BazSr1-z)2CoxFe2-2x(SiyGe1-y)1+xO7 (dans la formule, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1, et 0 ≤ z ≤ 1, à l'exclusion du cas où x = 1, y = 1, et z = 0, le cas où x = 1, y = 1, et z = 1, le cas où x = 1, y = 0, et z = 0, le cas où x = 1, y = 0, et z = 1, le cas où x = 0, y = 0, et z = 0, et le cas où x = 0, y = 0, et z = 1).
(JA) 金属空気電池の正極触媒に用いることができる新規な化合物を提供すること。 本発明に係るメリライト型複合酸化物は、一般式(BaSr1-zCoFe2-2x(SiGe1-y1+x(式中、0≦x≦1,0≦y≦1,0≦z≦1である。但し、x=1且つy=1且つz=0の場合、x=1且つy=1且つz=1の場合、x=1且つy=0且つz=0の場合、x=1且つy=0且つz=1の場合、x=0且つy=0且つz=0の場合及びx=0且つy=0且つz=1の場合を除く。)で表される。
