Abstract: A method for fabricating a high-temperature ceramic superconductor having a Y-Ba-Cu-O or other copper-oxide composition of comparable properties so as to render the ceramic porous to define interlaced diffusion channels throughout the entire body of the ceramic. As a consequence, oxygen, an essential component thereof, will in the course of firing the ceramic, diffuse throughout the interior of the body and thereby interact and become integrated with the crystal structure of the ceramic to form a superconductor having superior properties. The resultant porous ceramic body may be used as a superconductive device, or it may be ground into particles and dispersed as a filler in a binder acting as a plastic agent that can be extruded, molded, or otherwise shaped to create a Meisner-effect shield, a cylindrical superconductive bearing or other superconductive structure.
