| 简介 |
This superconducting wire is provided with a wire formed from a superconductor and with a superconducting stabilizer arranged in contact with the wire. The superconducting stabilizer is formed from a copper material which contains, in total, a 3 to 400 ppm by mass of one or more additive elements selected from Ca, Sr, Ba and rare earth elements (RE) and has a remainder of Cu and unavoidable impurities, wherein the total concentration of unavoidable impurities, excluding O, H, C, N and S which are gas components is 5-100 ppm by mass, and compounds including one or more selected from CaS, CaSO4, SrS, SrSO4, BaS, BaSO4, (RE)S and (RE)2SO2 are present inside the matrix phase. |
