Comprehensive review of the XRD data of the primary and secondary phases present in the BSCCO superconductor system: Part 1, Ca-Sr-Cu oxides

摘要

X-ray powder patterns for the phases in the CaO-SrO-CuO ternary system, along with the corresponding crystal structures, were obtained from the literature and from the Powder Diffraction File (PDF). Available X-ray diffraction (XRD) patterns were compared with each other and, when possible, with a simulated pattern for each phase, yielding a recommended reference pattern. The simulated powder patterns presented here deal with the phases found within the (Ca, Sr)O, (Ca,Sr)(sub 2)CuO(sub 3), (Ca,Sr)(sub 14)Cu(sub 24)O(sub 41), (Ca,Sr)CuO(sub 2), (Ca,Sr)Cu(sub 2)O(sub 3), and (Ca,Sr)Cu(sub 2)O(sub 2) solid solution series and are recommended for the PDF.
