Abstract
In a method for the manufacture of an encased high critical temperature superconducting wire by the 'powder in tube' method, prior to the introduction of a compressed rod of superconducting material into a silver tube, the rod is heat treated so that grains of unwanted phase are reabsorbed. The tube can be drawn more easily, and strands can be produced with a regular geometry and no defects. The wire is constituted by 15 .mu.m to 20 .mu.m thick filaments (30) with a form factor of more than 60.
