Description
Firing a long specimen in a thermal gradient furnace is an efficient way of looking for the fine details of synthesis/morphology behavior in Ag-''doped'' (Bi, Pb)-high temperature superconductors as a function of temperature and time. The 110 K, three-Cu-layer phase, begins to form apparently only upon the appearance of an eutectic-liquid at ∝822degC. The accompanying morphological changes are readily seen and interpreted by SEM/EDS of fractured surfaces. (orig.)
