dc.description.abstractCrystalline lead-free piezoelectric potassium niobate (KNbO<inf>3</inf>) powders have been synthesized through a modified solid-state reaction method. The thermal behavior of the K<inf>2</inf>C<inf>2</inf>O<inf>4</inf>-H <inf>2</inf>O and Nb<inf>2</inf>O<inf>5</inf> raw material mixture was investigated by thermogravimetric analysis (TGA) and differential thermal analysis (DTA). The X-ray diffraction technique (XRD) was used to investigate the phase formation and purity. The morphology of the powder obtained was characterized using a scanning electron microscope (SEM). The XRD pattern showed that the monophasic perovskite phase of KNbO<inf>3</inf> could be synthesized successfully at a temperature as low as 550 °C for 240 min, with an average crystallite size of 36 ± 8 nm. The SEM images suggested that the average particle size of the powder obtained was 278 ± 75 nm. © Springer Science+Business Media, LLC 2010.
