Abstract

Micron-scale platelet barium titanate was synthesized using a twostep molten salt and topochemical technique. Plate-like BaBi4Ti 4O15 was first synthesized as a precursor by molten salt synthesis. Then, Bi3+ in the precursor was replaced by Ba 2+ and formed perovskite-structure BaTiO3 through a topochemical reaction. The BaTiO3 single crystals have an average size of 5-10 μm and a thickness of 0.5 μm. The purpose of this article is to control the particle shape with desired structure. High aspect ratio BaTiO3 platelets are suitable templates to obtain textured ceramics (especially Pb(Mg1/3Nb2/3)O3-32.5PbTiO 3) by the templated grain growth process.
