Methods for implementing production of an oxide superconductor joined member, excellent in electric current transmission performance, without a need of going through particularly complex steps, are provided. When joining together oxide superconductors by use of a solder composed of an oxide superconducting material, a finally solidified portion of the solder is positioned in a region where a transmission path of electric current flowing between oxide superconductor base materials as joined together is not obstructed by, for example, disposing the solder on a face of the oxide superconductor base materials, other than butting surfaces of the oxide superconductor base materials, so as to straddle both the base materials like bridge-building. Current flow is also not obstructed by, for example, shaping junction faces of the oxide superconductor base materials such that at least portions of the butting surfaces thereof are in the shape of sloped open faces, parting from each other. Further, an oxide superconductor joined member is made by joining the base materials with each other through the intermediary of an oxide superconductor, serving as a binder, disposed on at least a face of the base materials, other than butting surfaces thereof.
A method of joining together oxide superconductors whereby, when joining the oxide superconductors by use of a solder composed of an oxide superconducting material, a finally solidified portion of the solder is positioned in a region where a transmission path of electric current flowing between oxide superconductor base materials as joined together is not obstructed by rendering at least portions of butting surfaces of the oxide superconductor base materials to be joined together into sloped open faces, parting from each other, and by disposing the solder over the sloped open faces after the butting surfaces other than those of the sloped open faces are butted against each other, thereby shifting non-superconducting particles, micropores and impurity constituents to an outer surface of the joined superconductors.
An oxide superconductor joined member obtained by joining oxide superconductor base materials with each other through the intermediary of an oxide superconductor, serving as a binder, interposed between angled and opposed sloped faces other than butting surfaces of the oxide superconductor base materials so that non-superconducting particles, micropores and impurity constituents are shifted to an outer surface of the superconductor joined member.
