Fund Project:

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.
