Abstract
A process of forming on a gold, silver or platinum metal surface of a substrate a superconductive crystalline mixed metal oxide thin film exhibiting superconductivity at a temperature in excess of 85.degree. K. A precursor of the superconductive thin film containing bismuth, strontium, calcium and copper is formed on the substrate surface and then thermally converted in the presence of oxygen to the superconductive thin film. Lead is added to the thin film precursor to raise the superconductivity of the completed thin film above 85.degree. K.
