ملخص: The formation of PZT from the oxides Pb3O4, TiO2 and ZrO2 in the presence of NiO, Fe2O3 and Ta2O5 additives has been investigated by thermal analysis (DTA and TG), X-ray diffraction and chemical techniques. It is shown that the formation of PZT is accomplished through several steps: decomposition and formation of Pb3O4 between 240 and 390 [deg]C; formation of PbTiO3 above 350 [deg]C and of its solid solutions at 650 [deg]C. The PZT solid solution appears without formation of PbZrO3.
