A process for the preparation of an electrical contact for superconducting ceramic.

摘要

Method of producing an electrical contact between a supply of current and a part made of superconducting ceramic type rba2 cu3 oy, where r designates a lanthanide chosen from among y, la, nd, sm, eu, gd, ho, er, tm, yb, and, where y is between 6, 9 and 7, the process according to which is deposited on said piece of a layer of a material based on resin containing the silver, dried and is carried out under oxygen a heat treatment comprising a heating at a temperature higher than 900degré c. and cooling with a bearing 450degré c corresponding to the atmosphere prevents reoxygenation of the said ceramic,....
