The Bi–(Pb)–Sr–Ca–Cu–O superconductor has been fabricated into tapes without a sheath and into multifilamentary wires and tapes with a Ag sheath. Superconducting properties, workability, the possibility of forming the superconducting phase in a long wire, morphology, effects of compacting and effects of c-axis alignment, to name a few, have been studied. Tape specimens prepared by combination and repetition of cold work (or cold press) and sintering showed a critical current density, Jc, as high as 5×103 A/cm2 at 77 K with good reproducibility and reliability, although these specimens are sufficiently thick (0.5–1.0 mm). (Generally, Jc, at the zero field is inversely proportional to thickness.) For these tape specimens (with Cu sheath), sintering and Jc measurement were performed after the Cu sheath was removed. X-ray analysis showed that most of these tape specimens consisted purely of the high-Tc phase (∼107 K). In these specimens, the c axis tended to align well. This c axis alignment may be a reason for the enhancement in Jc. On the other hand, the tape specimens cold-worked and sintered only once showed Jc as small as 102 A/cm2 the c axis showing no sign of the c axis alignment. A 1330-filament Bi–Pb–Sr–Ca–Cu–O wire with a Ag sheath has been successfully fabricated. This multifilamentary wire shows a critical temperature, Tc of ∼105 K. A multifilamentary tape specimen fabricated by a combination of cold working and sintering showed a Jc of 1.05×103 A/cm2 at 77 K.
