- W2314135245 abstract "Silver sheath process has been applied to the fabrication of oxide superconductor wires. In the present study, the possibilities of using the copper sheath are investigated from the view points of reactivities of YBa2Cu3O7-x (YBC) with copper metals. After hot-pressing of YBC powders enclosed in a copper tube in the temperature range 400° to 800°C under 200kg/cm2 for 1h, the reaction layers were examined by optical microscopy, SEM, XRD, EPMA, etc.. The reaction began above 600°C and the oxygen component in YBC oxidized the copper surface to produce Cu2O. BaCu2O2 formed in the YBC side. YBC-Cu powder mixtures were hot-pressed in the same manner as the above. Cu2O formed chiefly at 90-10wt% composition. For more than 30wt% of Cu, YCuO2 and BaCu2O2 having monovalent Cu were produced by the reaction with Cu2O. In order to prevent such reactions, gold or silver electroplating was applied to the inner surface of the copper tube. The electroplating of gold of 1μm or silver of 20μm prevented the reactions during hot-pressing at 700°C. The lower Po2 in the copper tube led to the decomposition of YBC to give oxygen gas and the tetragonal phase. When the oxygen gas (1.5kg/cm2) was supplied to the copper tube, YBC kept the orthorhombic structure and its superconductivity after the hot-pressing at 700°C." @default.
