Abstract
During sintering, superconducting copper-oxide films commonly have a high chemical activity with substrate materials, which results in poor superconductivity. In this research, the substrate is prepared by coating multiple non-superconducting Y-Ba-Cu-O films on alumina. The superconducting Y-Ba-Cu-O thick films were prepared by mixing powders Y2O3, BaCO3 and CuO, making a paste by mixing this noncalcined mixture with solvent, coating it on to a film-coated substrate using a painting or printing method, and then sintering the specimen. The thick films have positive superconductive characteristics at high temperatures.Keywords
