초록
We report the impact of Ba sources in the sonochemically activated solid-state synthesis of BaTiO3 powders. A water-solubleBa(CH3COO)2 and TiO2 powders were sonochemically mixed in aqueous medium with controlled pH values and subsequentlycalcined following a drying process. For a comparative study, solid-state BaCO3 powders were also used to synthesize BaTiO3powders under the same ultrasonication, drying, and calcination conditions. Phase conversion ratio to BaTiO3 and structuralproperties of the resulting powders for each case were characterized and compared in detail. We expect that this study willbe helpful in understanding the process for synthesizing and doping BaTiO3 powders using water-soluble raw materials
Abstract
We report the impact of Ba sources in the sonochemically activated solid-state synthesis of BaTiO3 powders.

For a comparative study, solid-state BaCO3 powders were also used to synthesize BaTiO3powders under the same ultrasonication, drying, and calcination conditions. Phase conversion ratio to BaTiO3 and structuralproperties of the resulting powders for each case were characterized and compared in detail. We expect that this study willbe helpful in understanding the process for synthesizing and doping BaTiO3 powders using water-soluble raw materials
