摘要：

The Bi2Sr2CaCu2O(x) phase was synthesized by the solid state reaction of oxides and carbonates. Powders with 2.5 and 5 wt% metallic Ag additions were also synthesized. The powders were cold pressed into pellets, which were hot isostatically pressed at a pressure of 105 MPa in an argon atmosphere at 850-degrees-C. The resultant pellets were fully dense. No decomposition of the Bi2Sr2CaCu2O(x) phase was apparent. Ag was present primarily at grain boundaries. Annealing in 1% oxygen/99% argon at 600-degrees-C raised T(c) from 76 K for the as-isostatically-pressed specimens to 83 K.
