<p>Disclosed is a composite material comprising a superconducting oxide in association with a ductile metal; the superconducting oxide formed of at least one metallic element and oxygen; the ductile metal having a lower oxidation potential than those metallic elements and having the ability to dissolve oxygen in the liquid phase or diffuse oxygen in the solid phase; and the ductile metal being present in a continuous phase as at least 50 % of the composition. Also disclosed is a method of forming such composite materials which includes forming a mixture or alloy of the ductile metal and the metallic elements and subjecting the mixture to an oxidizing atmosphere for a sufficient period of time and at a sufficient temperature to cause the metallic elements to oxidize to form the superconducting oxide but not to oxidize the ductile metal.</p> |
