ABSTRACT:
A process for the preparation of oriented, ceramic oxides from a bilayer structure of a polycrystalline superconducting ceramic oxide and a second ceramic oxide material having a lower melting point than the superconducting ceramic oxide. The process comprises the steps of preparing a substrate, depositing the superconducting ceramic oxide and second ceramic oxide in alternate layers, and heat treating the resulting composite structure to obtain an oriented structure whereby the c-axes of the unit cells of the crystallites are predominantly normal to the surface of the substrate.
