Properties of Bi-Pb-Sr-Ca-Cu-O glass-ceramic fibers formed by glass-drawing method

Flexible Bi-Pb-Sr-Ca-Cu-O glass fibers were prepared by the glass-drawing method. They showed superconducting properties after crystallization by heat treatment. The T c and J c values of the fibers were very sensitive to starting compositions and heat treatment conditions. The fiber with the starti...

Zusammenfassung:Flexible Bi-Pb-Sr-Ca-Cu-O glass fibers were prepared by the glass-drawing method. They showed superconducting properties after crystallization by heat treatment. The T c and J c values of the fibers were very sensitive to starting compositions and heat treatment conditions. The fiber with the starting composition of Bi 2.1 Pb 0.9 Sr 2 Ca 2 Cu 3 O y showed superconductivity with a J c =1480 A/cm 2 (77 K, zero magnetic field).
