ABSTRACT:
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.
