Abstract
A method for producing an oxide superconductor by partially melting and solidifying the precursor of the oxide superconductor is a method wherein the precursor is placed on a substrate material containing pure metal or a compound which is meltable in the precursor when the precursor is in a partially molten state, and partially melting and solidifying the precursor in said state.

A method for producing an oxide superconductor comprising:
- placing a precursor of an oxide superconductor in a state where it is on a substrate material containing pure metal or a compound which is meltable in the precursor when the precursor is in a partially molten state, and producing the oxide superconductor by partial melting and solidifying the precursor in said state.
A substrate material for supporting a precursor of an oxide superconductor, wherein the substrate material is used for a process for producing an oxide superconductor by solidification from a partially molten state of a precursor of an RE-Ba—Cu—O based oxide superconductor, and RE represents a rare earth element, and the substrate material is a material which contains Ba or Cu but does not contain a rare earth element in the partially molten state.
An RE-Ba—Cu—O based oxide superconductor, wherein RE represents a rare earth element, and the oxide superconductor includes a portion, which is solidified after melting and contains one of or both of Ba and Cu but does not contain a rare earth element, on an outside face of the oxide superconductor, and the solidified portion corresponds to a substrate material which is used for supporting a precursor of the RE-Ba—Cu—O based oxide superconductor when the precursor was melted and solidified.
