Abstract
A method of manufacturing an electrical contact between a current lead and a part made of a superconductive ceramic of the type RBa.sub.2 Cu.sub.3 O.sub.y, where R designates a lanthanide chosen from Y, La, Nd, Sm, Eu, Gd, Ho, Er, Tm, Yb, and Lu, and where y lies in the range 6.9 to 7, in which method a layer of a material based on a silver-containing resin is deposited on said part, the part is dried, and is then heat treated in oxygen by being heated to a temperature greater than 900.degree. C., and then cooled, with the temperature dwelling at 450.degree. C. for a certain length of time corresponding to the phase during which said ceramic is reoxygenated.
