Abstract: Cold pressing of Ag clad Bi 2223 superconducting tapes was systematically studied.The results showed that cold pressing was effective to fabricate tapes with good texture and high J C values.The optimum technical parameters are sintering thress times at 838℃ for 60h and pressing twice with pressure 2 0 GPa and 2 5 GPa for the first and second compaction respectively.Reduction rate of cold pressing was 1 5×10^-4 mm/s.
