Abstract
A process for producing a compound-based semiconductor wire having a high mechanical strength and which can be coiled so as to be cooled efficiently. A starting composition is formed by blending at least one metal powder selected from among Nb-based and V-based particles having at least a partial surface coating of an alloy or metal selected from Cu-Sn-based and Ga-based metal layers with at least one of Cu-based, Sn-based, Ga-based, Cu-Sn-based and Cu-Ga-based metal or alloy powder. The cross-sectional area of the composition is reduced followed by a heat treatment. The composition is then drawn into a wire of desired diameter.
Claims8
A process for producing a Nb.sub.3 Sn or V.sub.3 Ga compound-based superconductor wire comprising the steps of:
- forming a composition by blending at least one metal powder selected from the group consisting of Nb-based and V-based particles at least a part of the surface of which is covered with at least one layer selected from the group consisting of Cu-Sn-based and Ga-based metal layers with at least one metal powder or alloy powder selected from the group consisting of Cu-based, Sn-based, Ga-based, Cu-Sn-based and Cu-Ga-based;
- reducing the cross-sectional area of said composition;
- heat treating said composition;
- and drawing the heat-treated composition into a wire.
