Low Temperature Wet-Chemical Synthesis BaTiO₃ Nano-Particles by Tetra-N-Butyl Titanate [Ti-(O-C₄H₉)₄]

Abstract:

Barium titanate nano-particles were prepared by heating the mixture of barium hydroxide aqueous solution and titania derived from the hydrolysis of Tetra-n-butyl Titanate [Ti-(O-C4H9)4]. The well-crystallized cubic phase BaTiO3 fine particles were obtained by heating at more than 328 K for 24 h. The morphology and size of the obtained nano-particles depended on the heating temperature and the reaction molar ratio Ba/Ti. In addition, the secondary particles with the larger size were obtained at a lower heating temperature. It is considered that the nucleation process of BaTiO3 depended on the heating temperature and the reaction concentration.
