  • Ceramic high temperature superconductor in bulk form, and method of manufacturing the same
    Patent number: 5032569
    Abstract: A novel ceramic high temperature superconductor which has at least one phase with the composition (SE)Ba.sub.2 Cu.sub.4-x O.sub.8.+-.y, where SE is a trivalent rare earth atom, x.ltoreq.0.5, and y.ltoreq.1. The novel superconductor is distinguished by high thermal stability. Where the rare earth atom is Y (yttrium), if x=0 and y=0.01 a ceramic is produced which is stable up to about 800.degree. C., and has a transition temperature of 80.degree. K.
