Silver-sheathed Bi(Pb)2223 tapes have been developed as the first-generation high- superconducting material. Generally, a long-time sintering condition exceeding 100 h at in has been fixed for more than 20 years to prepare Bi(Pb)2223. In addition, there are few studies on the optimization of during sintering. In the present study, a low synthesis was applied for fabrication of the Bi(Pb)2223 bulks and tapes. The silver-sheathed Bi(Pb)2223 tapes were prepared by sintering under various conditions including hot isostatic pressing treatment. Fine Bi(Pb)2223 grains were observed in the samples when the first sintering was performed in . This led to densification of oxide core by second sintering using hot isostatic pressing treatment , resulting in improvements of sharpness of superconducting transition and at 77 K.
