In a process for producing an elongate body of longitudinally aligned acicular crystals (3) of the superconducting substance SEBa2Cu3O6.5+y with SE = rare earth metal, O<y<1, fine-grain powder (1) having a particle diameter of 0.1 to 5 mu m is sintered for 1 to 100 hours at a temperature from 600 to 850 DEG C, applying a pressure from 100 to 5000 bar. To produce a filament conductor, the powder is filled into an Ag tubule (4), drawn and pressure-sintered at 800 DEG C/10 hours under 2000 bar. <IMAGE> |
