Abstract
Articles are disclosed in which an electrically conductive layer on a substrate exhibits a superconducting transition temperature in excess of 30.degree. K. Conductive layers are disclosed comprised of a crystalline rare earth alkaline earth copper oxide. Processes of preparing these articles are disclosed in which a mixed metal oxide precursor composition is coated and heated to its thermal decomposition temperature to create an amorphous mixed metal oxide layer. The amorphous layer is then heated to its crystallization temperature.
