Abstract

We report the impact of Ba sources in the sonochemically activated solid-state synthesis of BaTiO3 powders. A water-soluble Ba(CH3COO)2 and TiO2 powders were sonochemically mixed in aqueous medium with controlled pH values and subsequently calcined following a drying process. For a comparative study, solid-state BaCO3 powders were also used to synthesize BaTiO3 powders under the same ultrasonication, drying, and calcination conditions. Phase conversion ratio to BaTiO3 and structural properties of the resulting powders for each case were characterized and compared in detail. We expect that this study will be helpful in understanding the process for synthesizing and doping BaTiO3 powders using water-soluble raw materials.


Keywords: BaTiO3, Powder, Sonochemical, Solid-state reaction.
