  • Method for synthesis of high-temperature Hg-Ba-Ca-Cu-O (HBCCO) superconductors
    Patent number: 5578551
    Abstract: The present invention is a controlled vapor/solid reaction process for the synthesis of samples of bulk compositions with a structure defined by the homologous series HgBa.sub.2 Ca.sub.n-1 Cu.sub.n O.sub.2n+2+.delta. [Hg-12(n-1)n] with n=2, 3, . . . with up to 75 to 90% Hg-1212 and 65 to 75% Hg-1223 by volume, which display sharp superconducting transitions up to 135 K.
