Abstract:
A method of producing flexible fibers of a superconducting material, comprising:melting a superconducting material in a furnace containing a heating space;heating the melted superconducting material to a temperature above its melting point to form a stream of melted superconducting material;dropping the stream of the melted superconducting material into a vertically extending barrel of a nozzle;heating a fiberizing gas to a temperature ranging from 150.degree. F. to 750.degree. F.;blowing the heated fiberizing gas downwardly through the barrel of the nozzle at a sufficient rate to transform the dropped superconducting material in the barrel into fine ligaments which cool and solidify in the barrel to form flexible superconducting fibers; andcollecting the flexible superconducting fibers.
