<p>A process for producing a superconducting oxide wire which has even performances throughout so that a wire of an intended length can be taken out thereof. The process for superconducting oxide wire production comprises: a drawing step in which a wire formed by sheathing a precursor powder for a (Bi,Pb)-2223 superconductor with a metallic sheathing material is drawn; a first rolling step in which the wire which has undergone the drawing step is rolled; a first heat treatment step in which the wire which has undergone the first rolling step is heat-treated; a second rolling step in which after the first heat treatment step, the wire is rolled; and a second heat treatment step in which after the second rolling step, the wire is heat-treated. The process further includes, between the first rolling step and the second heat treatment step, a step in which any sheath-deficient part in the outer surface of the sheathing material is filled with a material comprising silver as the main component.</p> |
