Fabrication of YBa2Cu3O7-x Filaments by Extrusion of a Cu3O3Ba2Y(meoEt)7 (meoEt = 2-Methoxyethoxide) Precursor
Published online by Cambridge University Press: 28 February 2011
Abstract
YBa2Cu3O7-x filaments, with a zero resistance Tc of 89.5 K and a Jc of 225 A/cm2 in zero field at 77 K, were prepared from precursor filaments fabricated by extrusion of a polymeric Cu-Ba-Y precursor. The precursor was prepared by reaction of linear a (CuO)n polymer with Y and Ba alkoxides in non-aqueous solvents. Characterization of the precursor and superconducting filaments, along with the optimum extrusion and pyrolysis conditions, are described.
