Abstract:
A process for texturing an HTc superconductor of the matrix 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 0.ltoreq.x.ltoreq.0.4 and y is 0, 1 or 2 comprising the following steps carried out in succession:raising the temperature of said superconductor from room temperature to the melting point of said superconductor material,maintaining the temperature of said superconductor constant at said melting point of said superconductor material for a relatively short time,varying the temperature of said superconductor between said melting point of said superconductor material and its synthesis temperaturemaintaining the temperature of said superconductor constant at said synthesis temperature of said superconductor material for a relatively long time, andreducing the temperature of said superconductor from said synthesis temperature of said superconductor material to room temperature,in which process the step of varying the temperature of said superconductor between said melting point of said superconductor material and its synthesis temperature comprises:sudden cooling of said superconductor from said melting point of said superconductor material to an end of cooling temperature lower than said synthesis temperature of said superconductor material, andheating said superconductor from said end of cooling temperature to said synthesis temperature of said superconductor material.
