    摘要: The present invention provides a process for producing a superconducting material capable of elevating the Tc of oxide superconductors, in paticular Bi-based superconductors. The feature of the present invention resides in a process for producing an oxide superconductor, in which a intermediate product or a product showing superconducting property is treated with a solution containing a compound having a reducing or oxdising function. As the compound having a reducing function, compounds having two or more enolic hydroxy groups, cycloaliphatic polyhydric alcohol compounds or inorganic type reducing compounds are preferred. As the compound having oxidizing function, there can be mentioned, for example, carbonyl compounds, ozone, hydrogen peroxide, organic peroxide, dimethylsulfoxide and permanganate.
