Lead Titanate has been prepared by a sol-gel method using titanium tetrabutoxide and lead acetate in stoichiometric proportion. It was found that the seeding with solid PbTiO3 nanometersize particles (5 and 10 wt%) into the precursor solution plays a crucial role during crystallisation. At 380 degrees and 400 degreesC, the fraction of crystallisation of the PbTiO3 perovskite phase for seeded sample is much higher than that corresponding to the unseeded one. Unseeded gel remained almost amorphous at 400"C, whereas the 5 and 10 wt% seeded gel was approximate to 50 and 85% crystalline. Besides, while unseeded calcined gels exhibit clearly the presence of pyrochlore phase at 425 degreesC, this phase was not detected for the 5 wt% calcined seeded gel.
