Abstract

Hydrothemal synthesis of PbTiO3 has been investigated. A comprehensive thermodynamic model for heteroge-nous reacting solid-aquous system has been used to predict the optimum condition for the synthesis. Synthesis were performed using lead acetate trihydrate as Pb source crystalline TiO2 as Ti source and KOH as minerali-zer. The synthesis has been examined at low temperature (16$0^{\circ}C$) Phase pure perovskite PbTiO3 has been obtained at high pH(above 0.5 mol KOH). The morphology of PbTiO3 was acicular shape. It has been found sible for a distortion in the c direction. The water is gradully released on annealing the powder to 40$0^{\circ}C$ and the normal crystallographic properties are restored.
