Abstract

Monodispersed PZT fine particles were obtained from the condition which 0.2Pb (OC3H7)2/EtOH, 0.108Zr(OC4H9)4/EtOH and 0.092 Ti (OC2H5)4/EtOH were refluxed for 5 hrs at 76$^{\circ}C$ and hydrolyzed with 0.1-0.4 H2O/EtOH. The monodispersed particle was amorphous and crystallized to the tetragonal PZT phase when heated at $600^{\circ}C$. Particle size was about 0.55${\mu}{\textrm}{m}$ in 0.3 H2O/EtOH and 0.3${\mu}{\textrm}{m}$ in other cases. Relative density of sintered body at 90$0^{\circ}C$ and 100$0^{\circ}C$ was 93.5% and 98%, respectively.
