摘要	The effect of Pb content and particle size of precursor powders has been studied to improve the grain growth and texture of Bi-2223/Ag tapes. The Pb content and particle size of precursor powders dominate the amount of liquid phases, and thus affect the value of J(c) with a variation of heat treatment condition. The best values of J(c) reached 53 kA/ cm 2 at 77 K and 0 T. after 210 It heat treatment at 839 degreesC and two times intermediate pressing. It suggests that the improvement of J(c) characterized from high fraction of Bi-2223 with enlarged crystallites is attainable by optimizing the processing variables of precursor powders.
