Process for producing bismuth-based oxide superconductor, and superconductive wire |
摘要 |
An object of the present invention is to provide a method of manufacturing a bismuth-based oxide superconductor capable of obtaining a high critical current density and a superconducting wire containing a bismuth-based oxide superconductor manufactured by this method. The present invention is directed to a method of manufacturing a bismuth-based oxide superconductor containing a 2223 phase having a 2223 composition in a composition Bi-Sr-Ca-Cu or (Bi,Pb)-Sr-Ca-Cu, comprising a first step of charging a raw material containing a 2212 phase having a 2212 composition in a composition Bi-Sr-Ca-Cu or (Bi,Pb)-Sr-Ca-Cu with a critical temperature of not more than 70 K into a metal sheath, a second step of performing plastic working on the metal sheath charged with the raw material and a third step of performing heat treatment on the metal sheath charged with the raw material. |
