ABSTRACT:
A method to manufacture bulk polycrystalline superconducting materials having properties closely related to the properties of a single crystal of the superconducting material is provided. The method includes forming an oriented anisotropic structure by spray casting an atomized precursor onto a ceramic substrate. The precursor may be atomized in a neutral atmosphere and the resultant structure oxidized. In another embodiment, the precursor is atomized in an oxidizing atmosphere and the subsequent oxidation step may be omitted.
