Preparation of phase‐pure PZT (Pb(Zr 0.52 Ti 0.48 )O 3 ) powders was achieved, in the presence of urea (CH 4 N 2 O), by homogeneous precipitation. Aqueous solutions of PbCl 2 , ZrOCl 2 ·8H 2 O, and TiCl 4 were used as the starting materials in the synthesis of phase‐pure PZT powders. Phase evolution behavior of precursor powders was studied by powder X‐ray diffraction (XRD) in air, over the temperature range of 90° to 750°C. The morphology of the formed powders was studied by scanning electron microscopy (SEM). Semiquantitative chemical analyses of the samples were performed by energy‐dispersive X‐ray spectroscopy (EDXS).
