Title: Process for preparing superconductive thick films

Abstract

This patent describes a process of forming an electrical conductor on a substrate capable of withstanding processing temperatures. It includes forming on the substrate a coating of a precursor of a crystalline electrical conductor chosen from the group consisting of a rare earth alkaline earth copper oxide and a heavy pnictide mixed alkaline earth copper oxide and converting the precursor to the crystalline electrical conductor by heating, characterized by the steps of preparing a solution comprised of volatilizable aqueous solvent and, as a solute, inorganic salts forming metal-ligand compounds of each of the metals forming the crystalline electrical conductor, the proportions of the solute metals corresponding to those present in the precursor coating and the ligands being inorganic ligands chosen to be volatilizable on heating, and spraying the aqueous solution to form discrete liquid particles each containing the metal as metal-ligand compounds in proportions corresponding to those present in the precursor coating.
