Abstract
The present invention provides an oxide superconducting wire including a component provided in the form of a tape and a metal tape. The component in the form of a tape has an oxide superconducting member and a metal coating member formed mainly of silver and coating a surface of the oxide superconducting member. The metal tape, bonded in a heat treatment (e.g., fusion- or diffusion-bonded) to a surface of the component in the form of a tape, does not contain any superconducting material and it is formed mainly of silver and it also contains at least one component other than silver.
Claims9
A method of manufacturing a superconducting wire, comprising the steps of:
- preparing a component in a form of a tape including a plurality of oxide superconducting members which make a multifilamentary structure having at least a superconducting phase, and a metal coating member formed mainly of silver, and coating said plurality of superconducting members, said component having a longitudinal dimension;
- and
- bring into contact with a first surface of said component in longitudinal dimension, a first metal tape free of any superconducting material, said first metal tape being formed of an alloy formed mainly of silver, and subjecting said component and said first metal tape to a heat treatment,
- wherein a thickness direction of said component is not covered by said first metal tape.
