Synthesis , crystal structure and vibrational spectra of Sr 0 . 5 Zr 2 ( AsO 4 ) 3

Abstract

Sr0.5Zr2(AsO4)3 arsenate was prepared and structurally characterized by powder X ray diffraction and by Raman and infrared spectroscopies. Its structure, which belongs to the Nasicon-type family, was refined by the Rietveld method in the R-3 space group, from X-ray powder diffraction data. The hexagonal unit-cell parameters were determined to be ah=8.965(2… (More)
