METHOD OF FORMING THICK FILM OF OXIDE SUPERCONDUCTOR

摘要

To provide an oxide superconductor thick film formation method that can enhance adhesiveness of a Bi2223 thick film to a body to be processed on which the Bi2223 thick film is formed, and increase a cross-sectional area of the Bi2223 thick film, without a decrease in Jc of the Bi2223 thick film. A mixture of a compound oxide having composition Bi2212 and Pb is applied to a surface of the body to be processed, and burned to form a first thick film. An oxide superconductor thick film expressed by a general formula (Bi, Pb) 2+a Sr 2 Ca 2 Cu 3 O Z (where -0.1 ‰ a ‰ 0.5) is formed on the first thick film.
