Abstract
Shock wave formation of superconductive ceramic oxide electric and magnetic circuit elements with improved microstructures and mechanical properties.
Claims32
In a method for producing superconducting electric and magnetic circuit components, the steps comprising:
- disposing powdered superconducting ceramic oxide between sheets of conductive metal in a shock dissipative backing environment;
- generating a supersonic shockwave generally normal to planes of said sheets of conductive metal and said layer of ceramic oxide to thereby compact said powdered ceramic oxide into a densified superconducting body having superconducting current paths therethrough enclosed in and integral with said sheets of conducting metal.
An article of manufacture, comprising shock compressed superconducting ceramic oxide sealed in an outer casing of conductive metal.
