Abstract:
     A process for preparing the high-purity barium titanate nanoparticles includes such steps as preparing high-purity water (deionized water), preparing the gel of n-titanic acid, adding barium source to synthesize barium titanate suspension, washing, regulating the mole ratio of Ba to Ti, and drying to obtain the product used as electronic ceramic powder. Its advantages are easy control, high granular uniformity, and high activity.
