Preliminary
Lab-Report
Aqueous solutions
of lead chloride (PbCl2), zirconium oxychloride
(ZrOCl2.8H2O) and titanium tetrachloride
(TiCl4), in appropriate
volumetric amounts, were used as the starting materials in the synthesis of
phase-pure
Pb(Zr0.52Ti0.48)O3 powders. Preparation of the phase-pure PZT powders were achieved, in
the presence of
urea (CH4N2O), by the chemical
powder synthesis technique of homogeneous precipitation.
Calcination and phase evolution behavior of PZT
precursor powders were studied as a function of temperature by
powder XRD (X-ray
diffraction) in an air atmosphere, in the temperature range of 90 to 750°C.
Morphological properties of
the synthesized Pb(Zr0.52Ti0.48)O3 powders were investigated by the SEM
(scanning electron
microscopy) studies. Qualitative chemical analysis of the
samples were performed by EDXS
(energy-dispersive X-ray
spectroscopy).
