Abstract
Production of a wire-shaped ceramic high-temperature superconductor based on (Y,SE)Ba.sub.2 Cu.sub.3 O.sub.6.5+y with SE=rare earth metal and 0<y<1, in which 80 to 95% by weight of an ultra-fine grained powder (1) of globulitic particles having a maximum diameter of 1 .mu.m are processed with 0.5 to 3% by weight of a powder (3) of needle- and plate-shaped particles having a length of 10 to 50 .mu.m and 4 to 20% by weight of an organic binder with solvent (5) to form a highly viscous slip (7) and is extruded to form a strand (10) having longitudinally oriented needle- and plate-shaped particles and this is dried in air, calcined and sintered to form a fiber (13).
