Title:
METAL BASE MATERIAL FOR OXIDE SUPERCONDUCTIVE THICK FILM AND METHOD FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/050826
Kind Code:
A1
Abstract:
A metal base material for an oxide superconductive thick film which comprises a non−magnetic alloy in the shape of a plate, a tape, a rod or a wire and, formed on at least one surface thereof, a NiO layer&semi and some methods for preparing the metal base material including a method which comprises a step of providing a composite metal material comprising a non−magnetic alloy in the shape of a plate, a tape or the like and, bound on at least one surface thereof, a Ni layer, a step of introducing the composite metal material into a furnace having an oxidizing atmosphere and heating it for a given time, a step of interrupting the oxidation, and a step of treating the resultant material with heat in vacuum or in an inert atmosphere, thereby allowing a Ni base ferromagnetic layer to disappear and simultaneously forming an unoxidized alloy layer having a uniform composition.
