| Abstract | Nearly 95 ~01% of the 110 K superconducting phase was formed by lead doping in a Bi-SrCa-Cu-0 system. The processed 110 K superconducting powders were used to produce long silver-sheathed tapes with a highly textured microstructure by rolling and prolonged sintering. The transport critical current density was measured at 4.0 K to be 0.7X lo5 A/cm2 (the corresponding critical current is 74 A) at zero field and 1.6~ IO4 A/cm2 at 12 T for HIlab. At 76 K, the critical current density reached a value of 1 X lo4 A/cm2 at zero field for HIlab and gradually decreased to 419 A/cm2 at 1 T. Excellent grain alignment in the a-b plane led to greatly improved critical current densities under a magnetic field. The relationship between the transport properties and the microstructure of the tapes is discussed. |
