N2 - The effects of Ba-doping on the critical current density (Jc) of Ag-sheathed tapes of (Bi,Pb)-Sr-Ca-Cu-O superconductors were studied for samples with nominal compositions of Bil.8Pb0.4Sr2.0-xBaxCa2.2Cu3.0Oz (x=O to 0.6). The Jc increased with a small amount of Ba-doping, while it decreased with a large amount of Ba-doping. The maximum value of the Jc was 17,400 A/cm2 at 77K in OT for x=0.1. Ba-doping improved the Tc value of the tape, resulting from the dissolution of Ba into the Bi2223 phase. The Jc increase with Ba-doping was due to the increase of the ratio of Bi2223 phase and the decrease of the size and quantity of impurity phases.
