Abstract

BaTiO₃ nanoparticles were sonochemically synthesized in ethanol-water mixture solution at low temperature. Different growth mechanisms of the BaTiO₃ particles were identified in aqueous solution and ethanol-water solution under ultrasonication. Nanocrystals firstly formed and then oriented aggregated into large particles in aqueous solution under ultrasonic irradiation. Compared to the synthesis in aqueous solution, the BaTiO₃ nanoparticles could be prepared at low temperature in ethanol-water solution. Furthermore, the oriented aggregation of BaTiO₃ nanocrystals was suppressed and the BaTiO₃ nanoparticles grew up from the Ti-based precursor through a dissolution-precipitation process.
