Patent number: 6311384Abstract: An oxide superconducting wire is obtained by performing plastic working and heat treatment of a metal pipe which is filled up with raw material powder of an oxide superconductor. In the plastic working step, the metal pipe is subjected to flat working so that the raw material powder flows in the longitudinal direction as well as the cross direction in the metal pipe. In this case, a draft of at least 80% and not more than 98% is selected in the flat working step, to further promote the cross-directional flow of the raw material powder, thereby further improving density of the raw material powder. Thus, the as-formed oxide superconducting wire exhibits higher critical current density.Type: GrantFiled: October 20, 1997Date of Patent: November 6, 2001Inventor: Hidehito Mukai
