Abstract: The pure perovskite-lead titanate powders were prepared by coprecipitation method. The ethanol solution of the Ti(OC₄H₉)₄ and methanol solution of the PbAc₂ were mixed at a 1:1 molar ratio of Pb to Ti. Under intensive stiring the mixed solution was added dropwise to the water followed by adding H₂O₂ solution. The pH of the solution was adjusted to 8.9～9.2. by adding NH₄OH. The resulted precipitate was washed with deionized water and then dried at 100℃. The dried material was pestled and calcined at temperature above 550℃ to yield PbTiO₃ powders.

Key words: PbTiO₃, powder, coprecipitation
