Abstract:
1. A method of manufacturing a superconducting wire, comprising the steps of: drawing a wire formed by coating raw material powder for a superconductor with a metal; rolling said wire after said step of drawing said wire; and sintering said wire after said step of rolling; wherein at least one interval between (i) said step of drawing said wire and said step of rolling or (ii) said step of rolling and said step of sintering, is up to three days; setting the temperature of a heater adapted to provide heat to said wire such that said wire is maintained at a substantially constant temperature of less than or equal to 300° C. for the entire duration of the at least one interval of up to three days; maintaining the temperature of said wire at a substantially constant temperature during the at least one interval of up to three days; and holding said wire in an interior volume of a container having a reduced pressure atmosphere to suppress CO wherein said holding said wire in a reduced pressure atmosphere occurs after said drawing and before said rolling; and wherein an entire duration from a beginning of said drawing to an end of said rolling is free of sintering.
