Pure perovskite of lead titanate powder (PbTiO₃) was successfully produced via the sol-gel process using lead and titanium glycolates as starting precursors, as directly synthesized by the OOPS process. The obtained lead titanate is tetragonal or the perovskite type, with high purity and with nearly zero moisture content. From the high-resolution mass spectra, the X-ray diffraction technique, and Raman-FTIR coupled with TGA-DTA, the lead-titanium glycolates underwent the sol-gel transition through the formation of Pb-O-Ti bonds. The structural transformation, from the tetragonal form to the cubic form, had a great influence on the electrical properties at 430°C, close to the Curie temperature of 490°C. The microstructure of PbTiO₃ was characterized by SEM; the particle shape transformed from an agglomerate sphere to a needle and fiber-like shape as the calcination temperature was increased above T_c.
