Abstract

In this work we investigated the phase formation and structural ordering of Ba $_{3}$ B $^{'}$ Nb $_{2}$ O $_{9}$ (B $^{'}$ $=$ Ca and Zn) perovskite powders obtained by a modified polymeric precursor route using X-ray powder diffraction and Raman spectroscopy. We obtained single phase complex perovskites at 900 $^o$ C. Williamson-Hall analysis and scanning electron microscopy showed that the powders have crystallites and particles of nanometric size.
