摘要:
A method of manufacturing a superconductor comprising a superconductive intermetallic compound of at least two elements, includes the steps of producing a composite precursor comprising at least one filament which comprises one of said elements and is embedded in and supported by a matrix material, coverting at least part of the matrix material to a substance comprising the remainder of said elements, and reacting together said elements to produce said compound.

A method of manufacturing a superconductor which contains a superconductive intermetallic compound of at least two elements, includes the steps of producing a composite precursor having at least one filament which contain at least one of said elements and is embedded in and supported by a ductile metal matrix material, passing the precursor into a molten bath containing the remainder of said elements which removes substantially all of the matrix material from said filament(s) and which replaces the removed matrix material with a substance comprising the remainder of said elements, and reacting together said elements to produce said compound.
摘要:
A rod conductor of normal material has superconductive filaments located in grooves extending in a helical path on the periphery of the rod. The mouths of the grooves are closed and the composite is a superconductor.
