Description
Results of convergent beam electron diffraction and energy dispersive x-ray (EDX) microanalysis of Bi/sub 1.2/Ca/sub 0.9/Sr/sub 0.9/Cu2O/sub y/ superconductor are reported. The structure is orthorhombic with a = 5.63 A, b = 5.4 A, and c = 38.2 A. The c parameter is different from those reported by other workers and suggests that two extra perovskite units a/sub p/, where a/sub p/ = 3.82 A, have been introduced leading to c = 10a/sub p/. EDX microanalysis shows that the Cu content of this phase is higher than that reported by other workers. It is suggested that the phase with c = 38.2 A may be the higher temperature (115 K) superconductor
