Abstract
A process for texturing an HTc superconductor of the matrix type based on silver and the superconductor material (Bi.sub.1-x Pb.sub.x).sub.2 Sr.sub.2 Ca.sub.y Cu.sub.1+y O.sub.6+2y where x.epsilon.[0; 0,4] and y.epsilon.{0, 1, 2} includes the following steps carried out in succession: raising the temperature of the superconductor from room temperature to the melting point of the superconductor material, maintaining the temperature of the superconductor constant at the melting point of the superconductor material for a relatively short period, varying the temperature of the superconductor between the melting point of the superconductor material and its synthesis temperature, maintaining the temperature of the superconductor constant at the synthesis temperature of the superconductor material for a relatively long period and reducing the temperature of the superconductor from the synthesis temperature of the superconductor material to room temperature. The step of varying the temperature of the superconductor between the melting point of the superconductor material and its synthesis temperature comprises sudden cooling of the superconductor from the melting point of the superconducto…
