Effect of Processing Factors on Critical Current Density in Bi2212/Ag Wires

Abstract:

Article Preview

Five kinds of double stacked 385 (55ⅹ7) filamentary Bi2212/Ag round wires and 55 filamentary tapes with different Ag ratios (silver area/superconductor area) have been fabricated via PIT method, and the effects of Ag ratio and processing factors on critical current density were studied. The effects of the maximum temperature and average filament diameter on critical current density were also studied. The wire of 0.74 mm diameter having Ag ratio 3.7 showed critical current density of 2,218 A/mm2 at 4.2 K, 0 T.
