Preparation of Plank-Like BaTiO3 by Hydrothermal Soft Chemical Process from Layered Titanate Precursors


Article Preview

The influence of processing parameters on the morphology of hydrothermally derived BaTiO3 powders was investigated. Layered H2Ti3O7 with plank-like morphology were used as the Ti-precursor materials. The BaTiO3 powders were characterized by XRD and SEM. Lower Ba/Ti ratio is benefit for preparation of BaTiO3 particles which retains the morphology of the precursor. The BaTiO3 particles obtained at 200°C for 24h were large, uniform, and plank-like particles. Extending the hydrothermal temperature or the hydrothermal time does not help to synthesize BaTiO3 powders of large size and uniform morphology.
