N2 - The BPSCCO powder with a nominal composition of Bi:Pb:Sr:Ca:Cu=0.96:0.24:1.0:1.1:1.6 prepared by the co-precipitation method was packed into a Ag tube. The tape was fabricated by plastic deformation. Optimized heat treatment conditions for the tape samples have been studied. The critical current density of the tape samples after the 3rd heat treatment was found to depend on the temperature of the 1st heat treatment. The maximum critical current density was 10, 500A/cm2 at zero field and 77K in the sample subjected to the 1st heat treatment at 845°C. The impurity phases with a particle size of 5-10μm, such as Ca-Sr-Cu-O and Ca-Sr-Pb-O, were present even in the sample with Jc=10, 500A/cm2.
