Title: Fabrication and characterization of dense YBa2Cu3O7-y superconducting wires by extrusion technique
Author: RAM, P; SAXENA, VR; RAMAMOHAN, TR
Abstract: YBa2Cu3O7-y superconducting powders were prepared by solid state reaction 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 appropriate binder-plasticizer-solvent system. The density of the sintered wires was 92% with a high T-c and J(c) of 91 K and 2014 A cm(-2) (77 K, zero field) respectively. In the presence of applied magnetic field the transport J(c) showed a marginal drop of about 25%. (C) 1998 Elsevier Science S.A. .
