Cubic perovskite-related phases in the ternary SrO-CuO-Nb2O5 system

摘要

A careful phase analysis study of cubic perovskite-related phases in the ternary SrO-CuO-Nb2O5 system has been carried out via the synthesis and compositional analysis of a range of specimens within the ternary SrO-CuO-Nb2O5 system. Powder XRD in conjunction with electron probe microanalysis (EPMA) has been used to determine whether the synthesized specimens are single phase or not and to determine the compositions of the various reaction products. Three quite distinct such solid solution phases have been found and their quite distinct electrical and diffraction characteristics investigated. (C) 2004 Elsevier Inc. All rights reserved.
