Abstract
A superconductor of the general formula A.sub.3 B, e.g. Nb.sub.3 Sn, is manufactured by mechanical fabrication of A filaments in a bronze containing B followed by heat treatment to form A.sub.3 B by solid state reaction from B diffusing through the bronze without melting of the bronze. A pure metal for stabilization is mechanically fabricated together with the other components and protected from diffusion thereinto of any of the other components by a barrier layer of A metal. Superconductor formation on the barrier layer of A metal during the heat treatment is avoided or reduced by surface treatment or surface coating which inhibits A.sub.3 reaction between A and B at the barrier.
