Monodisperse BaTiO3 powder was prepared by a hydrothermal process from a mi
xture of Ba(OH)(2) and Ti(OH)(4). In the process, the best synthesis condit
ions were a Ba(OH)(2)Ti(OH)(4) mole ratio of 1, the reaction temperature 18
0 degrees C, which produced the cubic crystal structure of BaTiO3 with 0.3
mu 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. (C) 2000 Kluwer Academic Publishers.
