Tetragonal barium titanate (BaTiO3) powder with a uniform size distribution was successfully prepared by an ion-exchange treatment followed by hydrothermal process, and with a high precursor concentration. Ion-exchange treatment of the bariumtitanium chloride led to the formation of the homogeneous Ba-Ti hydroxide sol. Then, hydrothermal (240 ℃ for 7 h) led to the preparation of BaTiO3 powders with a very narrow size distribution (90 ± 3 nm) and a very high tetragonal content (90%), which were confirmed respectively by scanning electron microscopy and differential scanning calorimetry. Further, using the regenerated resin to ion-exchange, the BaTiO3 yield reached 99%.
