PZT ceramic powders were successfully prepared from the mixture of PbO, ZrO2 and TiO2 or zirconium (IV) propoxide, titanium (IV) isopropoxide and lead acetate trihydrate by mechanochemical and modified sol-gel syntheses under different conditions. The formation of perovskite phase in the calcined PZT powder has been investigated by X-ray diffraction (XRD) technique. The (ZrxTi 1-x)O2 powders with nanometer grain size were synthesized at a temperature lower than that required in the conventional process. In the present work, Lead zirconate titanate [Pb(Zr0.52Ti0.48)O3, PZT] ceramics were prepared by sol-gel and solid-state reaction methods at a temperature as low as 450°C,600°C respectively with the particle size in the range of 100-150 nm, 30–50 nm,. Fully dense PZT ceramics with 97% of the theoretic density have been achieved from powders at a sintering temperature of 1100°C for 1 h. The dielectric and ferroelectric properties of the sintered PZT ceramic were measured and the results were satisfactoty.
