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.
