PRODUCTION OF OXIDIC SUPERCONDUCTOR PRECURSORS

摘要

A process for producing an oxidic superconductor precursor alloy which comprises mechanically alloying metallic elemental constituents of the oxidic superconductor in stoichiometric proportions and in the presence of a process control agent nondetrimental to the superconductor to provide a uniform mechanically alloyed product which is compacted and worked to provide a product form such as sire, tape or thin strip. This product form can then be given the configuration required for use (e.g. open coil) and then oxidized to provide the superconductor.
