| Popis: | 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 °C. Williamson–Hall analysis and scanning electron microscopy showed that the powders have crystallites and particles of nanometric size. |
