Oxide superconductor thick film has a defined composition which can be applied to a surface of a substrate or a base

摘要

Oxide superconductor thick film has the composition (Bi, Pb)2+aSr2Ca2Cu3Oz (where a = 0-5) which can be applied to a surface of a substrate or a base. No fracture surface is present next to a boundary surface between the substrate or the base and the thick film in the thick film.
