摘要： The present invention provides a Bi2223 based thick film that does not peel off when a thermal or a mechanical shock is applied to a base or an oxide superconductor thick film or the like in the middle of a manufacturing process and a method of manufacturing the same An oxide superconductor paste 1 having a mixing ratio of Bi2212 composition is applied to a base 3, dried, burned, and thereafter burned at a temperature approximate to its melting point to obtain a partially molten layer 4. Next, an oxide superconductor paste 2 having a mixing ratio of Bi2223 composition is applied to the partially molten layer 4, dried, burned, compressed by a CIP, and thereafter repeatedly burned and compressed for a predetermined number of times to obtain the base 3 having a desired superconductor thick film 5 formed thereon.

摘要： The present invention provides an oxide superconductor thick film which is formed on a substrate or a board and has a high Jc and Ic and a method for manufacturing the same. Predetermined amounts of materials containing elements of Bi, Pb, Sr, Ca and Cu are weighed, mixed and subjected to steps of calcining, milling, and drying, and thereafter an organic binder and an organic vehicle are added thereto to prepare a (Bi, Pb)2nullaSr2Ca2Cu3Oz, superconductive paste, which is applied to the surface of a substrate or a board in a thickness of 260 nullm or more and dried. Thereafter, the paste is first subjected to burning at temperatures of 835null C. to 840null C. for 100 hours, then pressurization, and further burning at temperatures of 835null C. to 840null C. for 100 hours, thereby preparing an oxide superconductor thick film having a film thickness of 130 nullm or more having a high Jc and Ic.
