摘要：

Long lengths of flexible silver-clad Bi-2223 high-T-c superconductors have been fabricated by the powder-in-tube technique. By improving process conditions dc transport measurements at liquid helium (4.2K) and hydrogen (20K) temperatures yield J(c)'s greater than 10(5) A/cm(2) at zero field and exceed 3 X 10(4) A/cm(2) at liquid nitrogen (77K) temperature in short tape samples. Detailed microstructural analysis and J(c) measurements with applied fields up to 20 T are reported. Coils have been fabricated from 1 meter lengths of conductor with J(c)'s at 77K approaching 10(4) A/cm(2). Measurements on small pancake coils made from 10 meter tapes are also reported.
