Sonochemical activation in aqueous medium for solid-state synthesis of BaTiO₃ powders.

ABSTRACT: BaTiO₃-based oxide compounds are important ceramic materials for multilayer ceramic capacitors. In this paper, we report a sonochemical activation process of BaCO₃ and TiO₂ in an aqueous medium for the synthesis of BaTiO₃ powders through a solid-state process. Owing to the physical and chemical effects of the ultrasonication in aqueous medium on the raw materials, BaTiO₃ powders could be successfully synthesized at relatively low temperatures through a solid-state reaction, which was significantly enhanced as compared to the case in ethanol medium. Detailed investigations on the resulting BaTiO₃ powders and ceramics were performed, and a model to understand the role of aqueous medium on the enhancement of the solid-state rea
