Title:

RE123 OXIDE SUPERCONDUCTOR AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2006/104287

Kind Code:

A1

Abstract:

Disclosed is a long RE123 oxide superconductor stably having excellent superconducting characteristics at liquid nitrogen temperature, which can be used as a strand for a single-core or multicore wire material. Also disclosed is a method for mass-producing such a superconductor. Specifically disclosed is an RE123 oxide superconductor characterized by being composed of a conductive layer containing an REBa₂Cu₃O_7-&dgr oxide superconductor, which is made by using a mixed raw material including at least RE₂BaO₄ and a Ba_x-Cu_y-O_z raw material, and a holding member for holding the conductive layer. In this connection, RE represents one or more elements selected from La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu and Y.
