Abstract

Ag-sheathed Bi₂Sr₂CaCu₂O_x (BSCCO) tapes were fabricated by a novel method which involves a combination of electrophoretic deposition and mechanical consolidation techniques. The critical current density of BSCCO tapes, measured using SQUID magnetometry, was found to be approximately 10⁵ A/cm² at 5 K. The mechanical properties and c-axis texturing of the BSCCO films in superconducting tapes was found to be improved by using BSCCO powders of smaller sizes and by introducing an interlayer of Ag-particles. Peel tests conducted on these samples suggested that the improvement in the fracture strength was related to the plasticity of the Ag-particle interlayer.
