Abstract

In the present work, we report a suitable approach for the preparation of BaTiO₃ nanostructures via the hydrothermal condition using Dolapix ET85 as surfactant. 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. In addition, uniform particles, size distribution and purity of samples are highly dependent on the applied hydrothermal condition.
