Synthesis and structural ordering of nano-sized Ba3B'Nb2O9 (B'= Ca and Zn) powders

Abstract

In this work we investigated the phase formation and structural ordering of Ba3B'Nb2O9 (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 oC. Williamson-Hall analysis and scanning electron microscopy showed that the powders have crystallites and particles of nanometric size.
