Synthesis And Structural Properties Of Lanthanum Doped Lead Zirconate Titanate Ferroelctrics
Lanthanum substituted Lead Zirconate Titanate ferroelectric materials were prepared using solid state reaction
method. The basic composition chosen for the present study is PbZr0.65Ti0.35O3. The constituent raw materials (mostly oxides
and carbonate) were weighed in proportions required to give the following selected compositions. (a) PbZr0.65Ti0.35O3 (b)
Pb1-xLax (Zr0.65Ti0.35)1-x/4O3, where x varies from 0.06 to 0.08 insteps of 0.01.The values of experimental density (measured
by Archimedes Principle), theoretical (XRD) density and relative density of isostatically sintered pellets were measured with
respect to La as substituent. Structural information of the samples was investigated using X-ray diffractometer.
Microstructural information of the samples were investigated using Scanning Electron Microscopy (SEM).
