Abstract
Process for the production of an elongate body of longitudinally aligned acicular crystals (3) of the superconducting substance REBa.sub.2 Cu.sub.3 O.sub.6.5+y, with RE=rare earth metal, 0<y<1, in which fine-grained powder (1) with a particle diameter of 0.1-5 .mu.m is sintered for 1-100 h at a temperature of 600.degree.-850.degree. C. with application of a pressure of 100-5,000 bar. For the production of a filament conductor, the powder is filled into a small Ag tube (4), drawn, and pressure sintered at 800.degree. C./10 h under 2,000 bar.
