| 摘要 |
The invention relates to solid bodies made of hightemperature superconducting material to which contact is made by solid, compact metallic conductors. To produce said solid bodies, high-temperature superconducting material is either melted completely or a melt is obtained from the oxides of bismuth, strontium, calcium and copper, and, optionally, of antimony and lead. The solid, compact metallic conductors made of silver, gold, a platinum metal or an alloy containing said metals are then partially encased in the melt and the melt is allowed to solidify. Finally, the solid body obtained is annealed together with the conductors in a first stage at temperatures of from 710 to 810.degree.C and in a second stage in an oxygen-containing atmosphere at temperatures of from 750 to 880.degree.C.
