Method of manufacturing superconducting wire

摘要

A method of manufacturing a superconducting wire includes the step of drawing a wire formed by coating raw material powder for a superconductor with a metal (S 6 ), the step of first rolling (S 8 ) rolling a multifilamentary wire after the step of drawing (S 6 ), and the step of first sintering (S 10 ) sintering the multifilamentary wire 1 after the step of the first rolling (S 8 ). At least one of an interval between the step of drawing (S 6 ) and the step of the first rolling (S 8 ) and an interval between the step of the first rolling (S 8 ) and the step of the first sintering (S 10 ) is less than seven days. With this method, a superconducting wire having high and uniform performance can be obtained.
