Ceramic powders of lead titanate, co- doped with copper (Pb0.9Cu0.1TiO3) and cobalt or zinc, of a perovskite structure were prepared by the sol-gel process by adopting the mode of the destabilization of colloidal solution. The effect of temperature and dopants on the structure of the obtained samples was studied by X-ray diffraction (RX), Raman spectroscopy and scanning electron microscopy (SEM). Analysis of the samples with fluorescence spectroscopy shows that Zn simultaneously occupies the sites A (Cu) and B (Ti) of the structure, creating oxygen vacancies. The effect of co-doping on the quadracity of the crystal structure was examined.
