Özet

Preparation of phase-pure PZT (Pb(Zr0.52Ti0.48)O-3) powders was achieved, in the presence of urea (CH4N2O), by homogeneous precipitation. Aqueous solutions of PbCl2, ZrOCl2. 8H(2)O, and TiCl4 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 degrees to 750 degrees 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).
