PURPOSE:To enable a compound superconduction stabilizing thin plate having a wide width costlessly by providing a copper-tin or copper-gallium alloy layer, a superconductor layer composed of niobium or niobium-titanium or vanadium, and a stabilizing metal layer composed of metal good conductors of copper, silver, aluminum etc. CONSTITUTION:Niobium (or niobium containing a small quantity of titanium) 2' and 3' are explosively bonded in both sides of a copper-tin (tin density of 5-15 weight %) alloy 1'. Or vanadium is explosively bonded in both sides of a copper-gallium alloy (gallium density of 10-20 atomic density). Furthermore, metal good conductors 4, and 5, for stabilizing of copper, silver, aluminum, etc. are explosively bonded in both sides of a cladding material of niobium/ copper-tin/niobium or vanadium/copper-gallium/vanadium formed in the first process. This enables a large thin plate to be easily obtained and a compound superconduction stabilizing thin plate obtained which has a good adherence between a superconduction layer and each stabilizing metal layer, and a good electric and thermal conductivity between the superconduction layer and the stabilizing metal layers. |
