Abstract

We report here the controlled synthesis of (111) twinned BaTiO3 microcrystallites, which are widely known for their (110) ferroelectric twins. This (111) twinned structure was obtained through a composite hydroxide mediated process by using amorphous TiO2 powders. A twin assisted re-entrant growth model is proposed to account for the microstructural aspects determined. It is considered that the (111) twins originate from the Ti–O octahedra of the amorphous TiO2 powders. The role of oriented aggregation is also discussed.
