Abstract

In this paper, experimental works in fabrication of Bi-2223 round wires are presented. Seven filament Bi-2223 round wires ranging from 1.0 mm to 0.3 mm in diameter were fabricated and studied. The critical current density J_c (77 K, self field) of round wires was of 10³A/cm² order. A correlation between J_c and wire diameter was observed. For round Bi-2223 wires, there is an optimal diameter at which J_c reaches peak value and the value of optimal diameter was found to be related to coarseness of precursor powder.
