ABSTRACT:
A citrate/ethylenediamine gel method for forming oxide superconductors of the Y-Ba-Cu-O, Bi-Ca-Sr-Cu-O, Tl-Ca-Ba-Cu-O system by employing the nitrates of the individual metals and citric acid. Ethylenediamine is then added to form gels. These materials then undergo calcination and sintering processes. The respective superconductors obtained possess a superconducting zero resistance temperature at 93K, 78K and 118K respectively.
