ABSTRACT:
A process for forming a composite high temperature superconductor copper wire, said process comprising the steps of (1) directing a submicron sized powder of a superconducting ceramic material through a length of copper tubing to coat the interior surface of said tubing with a uniform compact film of said powder, and (2) sintering said powder while passing oxygen through said tube and while maintaining the outside of said tube in an inert atmosphere. In a preferred embodiment an aerosol process is used to generate the submicron sized powder of the superconductor.
