Fine barium titanate (BaTiO3) powders were prepared by a microwave-assisted liquid phase process at ambient pressure. The process is simple, ecologically friendly, and economical. Titanium dioxide (TiO 2) and Barium hydroxide octahydrate (BaOH28H2O) were the only starting materials used, in order to avoid contamination. BaTiO3 powders were obtained as a single cubic phase from both microwave-assisted and conventional liquid phase processes. BaTiO3 powders synthesized by conventional liquid phase process were nonuniform in size. In contrast, BaTiO3 powders made by the microwave-assisted process consisted of fine uniform particles with a narrow size distribution. TGA analysis revealed that the lattice OH group content in BaTiO3 powders synthesized by the microwave-assisted process decreased with increasing reaction time.
