Abstract

By means of doping Ca₂CuO₃ powders into the Ag-sheathed (Bi, Pb)-2223 tape, we found that the Ca₂CuO₃ powder has little side effect on the J_c values of the investigated tapes. So the Ca₂CuO₃ powder as resistive barriers between filaments was introduced into the (Bi, Pb)-2223 multifilamentary tape by powder-in-tube method. A rectangular deformation process by using a four-rollers machine has been applied to prepare the wires. The results indicate that the transport a.c. losses were decreased by introduction of the resistive barrier, while the J_c of the tape with barriers was almost not deteriorated compared with the tape without barriers.
