    • A metal oxide manufacturing method includes the steps of preparing the metal oxide expressed by a general formula of AXBYCZDn, (where A represents at least one element selected from a group consisting of a rare earth element, yttrium and an element obtained either by substituting part of rare earth elements with alkali metals or alkali earth metals or by substituting part of yttrium with alkali metals or alkali earth metals, B represents an alkali earth metal, C represents copper or an element obtained by substituting part of copper with transition metals, and D represents oxygen, and where when X=1, Y=2 to 4, Z=2.7 to 6 and n=6 to 13), reducing the metal oxide expressed by the general formula, and halogenating the reduced metal oxide. Part of oxygen (D) of the metal oxide expressed by the general formula is substituted with the halogen elements.
    • 金属氧化物制造方法包括以下步骤:制备由通式AXBYCZDn表示的金属氧化物(其中A表示选自由稀土元素,钇组成的组中的至少一种元素, 稀土元素与碱金属或碱土金属或用碱金属或碱土金属取代部分钇,B表示碱土金属,C表示铜或通过用过渡金属代替铜的一部分而得到的元素,D表示 氧,当X = 1时,Y = 2〜4,Z = 2.7〜6,n = 6〜13),还原由通式表示的金属氧化物,并且还原金属氧化物。 由通式表示的金属氧化物的氧(D)的一部分被卤素元素取代。
