ABSTRACT:
Disclosed herein is a ceramic superconductor comprising a ceramic superconductive member, and a high-conductivity metal layer covering the ceramic superconductive member. At least one portion of the metal layer having low electrical conductivity or low thermal conductivity. Also disclosed is a method of manufacturing a ceramic superconductor, comprising the steps of filling a ceramic superconductor or a precursor thereof in a high-conductivity metal pipe, thereby forming a composite member, rolling the composite member into a ceramic superconductor element of a desired shape, which comprises a ceramic superconductive member and a high-conductivity metal layer covering the ceramic superconductive member, performing a predetermined heat treatment on the ceramic superconductor element, and alloying a predetermined portion of the high-conductivity metal layer, thereby rendering the portion less conductive either electrically or thermally.
