Description:

The present invention comprises a method for making a composite superconductor and a superconductor.

Superconducting filaments (using a material such as Bi2212) are embedded in a silver-containing matrix material (which may be substantially pure silver). Oxygen-containing filaments are also embedded in the matrix material with the oxygen containing filaments preferably being dispersed evenly among the Bi2212 wire. A surrounding reinforcement material contains the other elements and preferably seals the superconductor from the surrounding atmosphere. The composite superconductor is created using any suitable process, such as passing the constituents through one or more drawing dies. Once the materials are bonded together, the composite superconductor is subjected to one or more heat treatment processes. The oxygen within the oxygen-containing filaments reacts with the Bi2212 to form desired superconducting materials.
