    Abstract

    Powders of high-temperature superconducting materials in the Y-Ba-Cu-O, Bi-Sr-Ca-Cu-O, and Tl-Ba-Ca-Cu-O systems have been prepared by solid-state reaction techniques. Monolithic samples of these materials have been produced by both sintering and plasma-spraying techniques. Controlled oxygen annealing is generally required to optimize the superconducting properties. These monolithic materials exhibit superconducting transition temperatures that exceed 80 K, with the highest observed transition temperature (105 K) in the Tl-Ba-Ca-Cu-O system. The measured critical current densities are low, however, due to the presence of weak links in the form of grain-boundary material and microcracks.
