Abstract
YBa2Cu3O7-y superconducting powders were prepared by solid state react ion method and drawn in to uniform wires of different diameters (0.9-2 .5 mm) and lengths up to 10 m by extrusion technique using an appropri ate binder-plasticizer-solvent system. The density of the sintered wir es was 92% with a high T-c and J(c) of 91 K and 2014 A cm(-2) (77 K, z ero field) respectively. In the presence of applied magnetic field the transport J(c) showed a marginal drop of about 25%. (C) 1998 Publishe d by Elsevier Science S.A. All rights reserved.
