PURPOSE:To improve bond strength by bonding the bonding parts of noble-metal sheets with an adhesive consisting of a compd. contg. >=2 kinds of elements constituting an oxide superconductor. CONSTITUTION:The sheets 3 and 3' of noble metals such as Ag, Au and Pt having >=900 deg.C m.p. and >=50mum thickness are placed on a substrate 1 of stainless steel, etc., through an inorg. adhesive 2, a pasty adhesive 5 contg. >=2 kinds of elements constituting a superconductor based on Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O, etc., is applied on the overlapped ends 4 of the sheets, and the adhesive is baked to bond the sheets to the substrate. A slurry of the powder of the oxide superconductor based on Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O, etc., ethanol and a dispersant is then sprayed thereon to form a superconductor layer 6 having 50-5000mum thickness, and baked at about 800-1100 deg.C in a gaseous O2 current to obtain a plate-shaped oxide superconducting laminated body. |
