YBCO/Ag superconducting rods prepared by the unidirectional solidification method were dipped into molten silver in order to fabricate low resistance metal contacts on the surfaces of the superconductors. In the case of dipping into a pure molten silver, a copper deficient reacted layer was formed at the boundary between YBCO/Ag superconductor and molten silver, although the temperature of the silver melt was lower than the melting temperature of the YBa2Cu3Ox/Ag phase. The formation of this reaction layer can be suppressed by means of the addition of YBa2Cu3Ox powder into the molten silver.
