The preparation of long superconducting Y123 filaments is developed by using solution spinning for the precursor of the oxide. Long precursor filaments are prepared by dry spinning with a starting homogeneous aqueous PVA solution containing Y, Ba and Cu acetates. The as-drawn filament with 250 {mu}m, in diameter and 300 mm in length is pyrolyzed and partial-melted by using a tube furnace with a constant heating zone of 500 mm. A superconducting filament of 60 {mu}m in diameter and 200 mm in length with high J{sub c} of more than 10{sup 4} A/cm{sup 2} at 77 K and 0 T is obtained by controlling the partial melting.
