Abstract

Nano-sized barium titanate (BaTiO3) powders with ultra-high crystallinity have been successfully prepared by a hydrothermal condition at 170°C for only 2 h. In this study, the influence of processing parameters on the phase and the particle size of hydrothermally derived BaTiO3 powders was investigated. The powders were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), energy-dispersive X-ray spectroscopy (EDAX), field emission transmission electron microscopy (FETEM), selected area electron diffraction (SAED), high resolution transmission electron microscopy (HRTEM) and zetasizer measurement. As a matter of fact, the hydrothermal method guarantees the production of BaTiO3 nanoparticles with desired morphology for commercial applications. It was found that using Dolapix ET85 strongly enhances the crystallinity of BaTiOand stabilizes its crystal lattice. In addition, uniform particles, size distribution and purity of samples are highly dependent on the applied hydrothermal condition.
