Beschreibung
Zusammenfassung:	Method of making an electrical contact between a current input and a component made of superconductive ceramic of RBa2Cu3Oy type where R denotes a lanthanide chosen from Y, La, Nd, Sm, Eu, Gd, Ho, Er, Tm, Yb and Lu and where y is between 6.9 and 7, according to which process a layer of material based on a resin containing silver is deposited on the said component, drying is performed and a heat treatment is performed under oxygen, comprising heating to a temperature above 900 DEG C and cooling with a plateau at 450 DEG C corresponding to the stage of reoxygenation of the said ceramic.
