Abstract: The silver-sheathed Bi-Pb-Sr-Ca-Cu-O(Bi-2223) superconducting tapes have been fabricated by the powder-in-tube method. In the process,we investigated the effects of the particle size, rolling and pressing on Jc and found that the Jc value can be a ffected greatly by the three factors.

Key words: Ag-sheathed Bi-2223 tape, deformation, particle size
