Abstract :
The changes in the structural composition of each phase (sol, powder, film) of sol-gel derived PbTiO3 (PT) are reported as a function of thermal processing conditions and of type of catalysts introduced. The dense amorphous layers turn into crystalline perovskite phase after annealing at 400°C. PT powders have the same transformation at 300°C. A variety of spectroscopic, chromatographic and wet-chemical means were used to evidence these transformations
