Abstract

Method of making an oxide superconductor multifilamentary wire (100), a method according to which the following operations are carried out: - "stage 0" is performed by introducing a powder of the said oxides, into a metal tube (3) of rectangular or square cross-section, this tube is subjected to a mechanical conversion in order to reduce its transverse dimensions while maintaining its profile, and it is sectioned into short-length stalks, - "stage 1" is performed by juxtaposing the said short-length stalks in a metal container (5) with a rectangular transverse profile, and the same mechanical conversion and the same sectioning are carried out as for the said "stage 0", - "stages 2, 3...n" are performed as for the said "stage 1", - "stage n" is thermally processed in order to sinter the said powder. <IMAGE>
