Abstract
In the present invention, a superconducting (sc) ceramic filament is enclosed in a silver sheath which is sealed therearound by applying silver powder between the surfaces of said sheath, pressing the surfaces and powder into contact and then applying sufficient heat to fuse them together, which heat is below the melting point of the surfaces and powder and then sintering the so enclosed ceramic filament, which upon cooling, forms a superconductor.
Claims13
A method for enclosing at least one superconducting (sc) ceramic filament comprising,
- a) placing at least one filament on a sheet of metal,
- b) wrapping said sheet about said filament to form a sheath therefor having closely spaced or overlapping surfaces,
- c) applying powder of at least one metal between said surfaces,
- d) pressing said surfaces and said powder into contact and
- e) applying sufficient heat to fuse said powder and said surfaces together to seal said sheath, which heat is below the normal melting point of the metal in said powder and surfaces.
