Abstract

Superconducting YBa2Cu3O7−x fibers were fabricated by the sol-gel method using modified metal alkoxides. To prepare precursors of a homogenous and viscous sol, Y and Cu alkoxides were modified with ethyl acetoacetate(EAA) and ethylenediamine(en), respectively. Their structures were determined by FT-IR and EXAFS. The sol prepared from modified alkoxides was spun into gel fibers by the spinning apparatus. They were subsequently fired to obtain superconducting fibers.
