ABSTRACT:
A method of making at least one low electrical resistance connection between a metal and a high T.sub.c superconducting ceramic part, said part being made from a ceramic powder which is placed in a mold, compressed, and sintered, wherein at least one volume of silver or gold powder corresponding to the shape of said connection and situated at the desired location is placed inside said mold in juxtaposition with said ceramic powder but without being mixed therewith, after which the compression and the sintering are performed under an atmosphere containing oxygen and at a temperature that is lower than the melting temperature of silver or gold.
