Superconducting thick films (200± 50 μ m) were prepared by coating method on Ag or polycrystalline MgO substrate. The paste for coating was a mixture of single 2223 phase powder, an organic binder (PSO or polyethylenegrycol) and organic solvents, and it was prepared by calcined powder of Bi1.8 Pb0.4Sr2Ca2Cu3. 2Oy . In the film from the PSO binder and Ag substrate high Tc and high Jc were obtained for 20h sintering time.
