ABSTRACT:
A method for the manufacture of a superconductive Nb.sub.3 Sn layer on a niobium surface for high frequency applications in which the niobium surface to be provided with an Nb.sub.3 Sn layer is first anodically oxidized, the niobium oxide layer produced in this manner then exposed to a tin vapor atmosphere in such a way that a tin layer is formed on the niobium oxide layer, and finally, the niobium surface is heated to a temperature of between 930.degree. and about 1400.degree. C for forming the Nb.sub.3 Sn layer.
