| description | Simple but robust growth of spherical BaTiO<sub>3</sub> nanoparticles with uniform nanoscale sizes is of great significance for the miniaturization of BaTiO<sub>3</sub>-based electron devices. This paper reports a TiO<sub>2</sub>-seeded hydrothermal process to synthesize spherical BaTiO<sub>3</sub> nanoparticles with a size range of 90−100 nm using TiO<sub>2</sub> (Degussa) and Ba(NO<sub>3</sub>)<sub>2</sub> as the starting materials under an alkaline (NaOH) condition. Under the optimum conditions ([NaOH] = 2.0 mol L<sup>−1</sup>, <i>R</i><sub>Ba/Ti</sub> = 2.0, <i>T</i> = 210 °C and <i>t</i> = 8 h), the spherical BaTiO<sub>3</sub> nanoparticles obtained exhibit a narrow size range of 91 ± 14 nm, and the corresponding BaTiO<sub>3</sub>/polymer/Al film is of a high dielectric constant of 59, a high break strength of 102 kV mm<sup>−1</sup>, and a low dielectric loss of 0.008. The TiO<sub>2</sub>-seeded hydrothermal growth has been proved to be an efficient process to synthesize spherical BaTiO<sub>3</sub> nanoparticles for potential capacitor energy-storage applications. |
