Preparation of Pb-Doped Bi-Sr-Ca-Cu-O Superconductors by a Hot-Press Method

Abstract

Synthetic conditions of Pb-doped Bi-Sr-Ca-Cu-O oxide superconductors produced by a technique of a uniaxial hot-press method were studied. The quality of the samples was measured by means of X-ray diffraction analysis, secondary electron microscope measurement and density measurement. The hot-pressed sample showed a single 2223-phase with density close to the ideal value.
