Martin, D L; Benz, M G

The properties of superconductors of the niobium-tin type may be improved by the provision of flux trapping or pinning sites therein in the form of a dispersion of stable particles formed by the reaction between a metal such as zirconium for example, and a non-metal such as oxygen, nitrogen or carbon to form the corresponding metal oxides, nitrides or carbides. While the particle forming metal may be present as an alloying ingredient in either the tin bath through which the niobium strand is passed, or as an alloying ingredient in the niobium strand, where the superconductor is Nb/sub 3/Sn, it is preferred to use a niobium-zirconium alloy. In the process, a niobium-zirconium alloy strand is passed through a molten tin bath to form a tin coating thereon and subsequently heat treated in the presence of the non-metal reactant whereby an Nb/sub 3/Sn superconductive layer is formed containing the stable reaction product dispersion.
