For the purpose of the application of superconducting oxides, preparation of the long wire and tape with low dispersion of Jc is very important. We have been attempted to preparate the long superconducting oxide tape by pyrolysis of organic acid salts on metal tapes.
In this paper we describe a study of the preparation of c-axis orientated 123 phase Y-Ba-Cu-O superconducting thick film on Ag tape with about 10m length. This tape had 1.5×104A/cm2 and 9×104A/cm2 of critical current densities (Jc) at 77k OT and 4.2K OT, respectively. The dispersion of Jc value was very little.
