Abstract

The suspension spinning of a high Tc oxide superconductor by using PAN was studied to prepare a long filament with high Jc. The highest Jc of 1285 × 104 A/m2 at 77 K was obtained for the Y-Ba-Cu-O filament spun through PAN-DMF suspension medium containing the oxide of 92 wt%.

A high-Tc phase superconducting Bi-Pb-Sr-Ca-Cu-O filament was successfully prepared using a combined technique of suspension spinning and densification of the pyrolyzed filament by two stages of pressing and sintering. Zero electrical resistivity was achieved at 90 K and the Jc of the filament at 77 K was 55 ×104 A/m2.
