Preparation of Bi1.5SrCaCu2Ox Glass Fibers Using Melt-Quenched Glasses

Bi1.5SrCaCu2Ox glass preforms were prepared by the melt-quenching method, and their thermal characteristics and viscosity were investigated to determine the possibility of drawing them into glass fibers. Furthermore, Bi1.5SrCaCu2Ox glass fibers were drawn from glass preforms by the method that is ordinarily applied to optical fiber fabrication. The drawn fibers were very flexible, and the maximum length was 1200 mm.
