Process for producing superconducting thick film.

摘要

A process for producing a superconducting thick film including steps comprising subjecting a powder mixture of oxides or carbonates of Ba, Y and Cu each having an average particle size of less than 5 mu m to preliminary sintering, pulverizing the preliminary sintered mass into a powder having an average particle size of less than 10 mu m, and then admixing the pulverized powder with an organic vehicle to prepare a paste which is applied on a substrate and is sintered finally. The preliminary sintering is carried out at a temperature ranging from 700 DEG C to 950 DEG C, while the final sintering is carried out at a temperature ranging from 800 DEG C to 1,000 DEG C.
