Preparation of a high-density Bi-Sr-Ca-Cu-O ceramic with a single superconducting phase

Journal Article · · J. Solid State Chem.; (United States)

It is found that a high density ceramic of the Bi-Sr-Ca-Cu-O system with a single superconducting phase can be produced by quenching the specimen from the melt, and then annealing at an appropriate temperature in the oxygen atmosphere below the melting point. Here, a case of growing superconducting material with T/sub c/ of 85 K with nominal composition Bi:Sr:Ca:Cu = 2.2:1:2 is presented. The process thus has promise for producing high-quality, superconducting ceramic materials from the Bi-Sr-Ca-Cu-O system.
