A New Approach for the Fabrication of Tetragonal BaTiO₃ Nanoparticles.

For the first time, the BaTiO₃ nano-sized particles were obtained through solid-state reaction by employing the titanium oxide nanoparticle. Meanwhile, by using TiO₂ with micro-sized particles, the synthesized BaTiO₃ shows the micro-sized. The XRD pattern confirms that both BaTiO₃ nano-sized and micro-sized particles display the tetragonal structure.
