Compound superconducting wire and method of manufacturing the same. |
摘要 |
<p>A composite member is prepared which comprises a core (120) which will have a compound superconducting layer when heat-treated, and a stock for forming a stabilizing member (114) made of copper and surrounding the core (120). The composite member is heat-treated in an oxidizing atmosphere, thus forming a copper-oxide thin layer on the surface of the stock. Thereafter, the composite member is heat-treated in a non-oxidizing atmosphere or in an atmosphere having an oxygen partial pressure which is too low to allow the forming of copper oxide. As a result, a compound superconducting wire is made which comprises a member (11) including a compound superconductor, a diffusion-preventing layer (12) made of oxide and surrounding the member (11), and a stabilizing member (13) made of copper and surrounding the layer (12).</p> |
