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

Abstract:

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.
