Synthesis of nanocrystalline BaTiO۳ ceramics via hydrothermal condition and structural characterization by HRTEM and SAED

In the present work, we report a suitable approach for the preparation of BaTiO۳ nanostructures via the hydrothermal condition using Dolapix ET۸۵ 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 BaTiO۳ 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.
