The influence of an intermediate pressing process on the superconducting properties of Agsheathed Bi-Pb-Sr-Ca-Cu-O Superconducting tapes has been investigated. The critical Current density (Jc) was improved by the effect of a uniaxial pressing and sintering after the initial sintering. The maximum transport Jc at 77K under zero magnetic field was indicated as 2.9×104A/cm2, and that at 4.2K under zero magnetic field was indicated as 1.5×105A/cm2. The Jc at 4.2K and 12T has been shown to be 5×104A/cm2 when the magnetic field was applied parallel to the width of the tape, and 3×104A/cm2 under the condition of a perpendicular applied magnetic field. The reasons for these improvements are the formation of the high Tc (110K) single phase, a highly oriented texture with strong (00l) reflections and a compacted microstructure.
