High-{Tc} superconducting oxide fibers were fabricated by the sol-gel method. An aqueous solution of metal acetates was concentrated to form a viscous sol, from which gel fibers were spun. The gel fibers, 5 to 1,000 {mu}m in diameter, were converted to ceramic fibers by heating to 900{degree}C. The fired fibers ({Tc}(onset) of 94 K and {Tc} (end) of 62.2 K) were rough and had porous microstructures.
