Low temperature Wet-chemical synthesis BaTiO3 nano-particles by tetra-n-butyl titanate Ti-(O-C4H9)4

摘要：

　　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.
