Abstract

Effect of filament configuration and heat treatment of Bi2212/Ag round wire with low Ag ratio on the engineering critical current density (J_e) was reported. We have fabricated 55 × 7, 85 × 7, and 121 × 7 wires with different Ag ratio and evaluated J_e at various wire diameters. We have also changed the parameters of heat treatment. The effects of maximum process temperature (T_max) and soaking time at T _max and average filament diameter on the J_e were also studied. 121 × 7 wire of 0.95 mm diameter heat-treated at T_max = 888°C showed J_e of 858 A/mm² at 4.2 K, 0 T.
