Abstract

Cylindrical superconducting rods composed of Pb doped Bi-Sr-Ca-Cu-O, 10∼ 15 cm long and 10∼ 20 mm in diameter, were fabricated by a cold isostatic pressing (CIP) method. To evaluate their electric properties as current leads, critical current (Ic) and contact resistance to the ceramic superconductor were investigated. As a result of improvements, transport Ic value of 480 A at 77 K, that of more than 1000 A at 4.2 K, and contact resistance of less than 1.7×10−9 Ω (contact resistivity of less than 1.3×10−8 Ωcm2) were achieved.
