Claims
- 1. A process of preparing a high temperature superconducting composite conductor comprising:filling a rectangular-shaped tube of a noble metal with an oxide superconductor mixture; placing said filled rectangular-shaped noble metal tube into a secondary metal matrix containing a opening adapted for insertion of said filled rectangular-shaped noble metal tube; and, rolling said secondary metal matrix containing said filled rectangular-shaped noble metal tube to form a rolled product of a preselected thickness without any intermediate wire drawing steps.
- 2. The process of claimer further including heating said rolled product at temperatures and for time sufficient to form a high temperature superconducting composite conductor.
- 3. The process of claim 1 wherein said rectangular-shaped noble metal tube is of silver.
- 4. The process of claim 1 wherein said secondary metal matrix is copper.
- 5. The process of claim 2 wherein said rolled product is characterized as having a fill factor of at least 40 percent by volume.
- 6. A process of preparing to a high temperature superconducting composite conductor comprising:filling a rectangular-shaped tube of a noble metal with an oxide superconductor mixture; and, rolling said filled rectangular-shaped noble metal tube to form a rolled product of a preselected thickness without any intermediate wire drawing steps.
- 7. The process of claim 6 further including heating said rolled product at temperatures and for time sufficient to form a high temperature superconducting composite conductor.
- 8. The process of claim 6 wherein said rectangular-shaped noble metal tube is of silver.
- 9. The process of claim 6 wherein said rolled product is characterized as having a fill factor of at least 40 percent by volume.
