| Abstract: | Monodisperse BaTiO3 powder was prepared by a hydrothermal process from a mixture of Ba(OH)2 and Ti(OH)4. In the process, the best synthesis conditions were a Ba(OH)2/Ti(OH)4 mole ratio of 1, the reaction temperature 180°C, which produced the cubic crystal structure of BaTiO3 with 0.3  m size. The effects of synthesis conditions and the dispersion stability of powder were investigated. The reaction kinetics was also discussed from the experimental results. |
