摘要： A superconducting device according to the present invention has an oxide superconducting wire. The sintering density of an oxide superconductor in the oxide superconducting wire is at least 93%, preferably at least 95%, and more preferably at least 99%.

摘要： A method of manufacturing an oxide superconducting wire according to the present invention comprises a step (S1, S2) of preparing a wire formed by covering raw material powder of an oxide superconductor with a metal (3) and a heat treatment step (S4, S6) of heat-treating the wire in a pressurized atmosphere having a total pressure of at least 1 MPa and less than 50 MPa in the heat treatment. At a heat-up time before the heat treatment in the heat treatment step (S4, S6), pressurization is started from a temperature reducing 0.2% yield strength of the metal (3) below the total pressure in the heat treatment. Thus, formation of voids between oxide superconducting crystals and blisters of the oxide superconducting wire is suppressed while the partial oxygen pressure can be readily controlled in the heat treatment, whereby the critical current density can be improved.
摘要翻译：根据本发明的制造氧化物超导线的方法包括制备通过用金属（3）覆盖氧化物超导体的原料粉末和热处理步骤（S4，S6）形成的线的步骤（S1，S2））在热处理中在总压力为至少1MPa且小于50MPa的加压气氛中进行热处理。在热处理工序（S4，S6）中的热处理前的加热时间，从低于热处理总压力的0.2％的金属屈服强度的温度开始加压。因此，抑制氧化物超导结晶和氧化物超导线的起泡之间的空隙的形成，同时可以容易地在热处理中控制部分氧压力，从而可以提高临界电流密度。

摘要： A method for producing a superconducting wire material having a high resistivity layer outside a superconducting material, which is capable of easily forming a homogeneous high resistivity layer, a superconducting wire material and a superconducting device are provided.A raw material of superconducting wire material is coated with a first silver-containing metal to obtain a silver sheath member. This silver sheath member is coated with a non-silver metal free of silver. At least a part of the first silver-containing metal in the member coated with a non-silver metal and the non-silver metal are intermetallically compounded with each other. This intermetallically compounded metal is oxidized to form a high resistivity layer. The member having a high resistivity layer formed thereon is heat-treated to convert the aforementioned raw material to a superconducting material.
