The PZT composites are almost used with a dopant, a modifier or other chemical constituent or constituents like La, Mn, etc. to improve and optimize their basic properties for specific applications. Lead lanthanum zirconium titanium oxide (PLZT) was initially developed by Haertling et.al., as a promising novel electro-optic material. Since that time, studies have focused on various applications, ranging from capacitors, transducers, actuators and electrooptic switches to pyro-electric detectors etc, as it has high dielectric constant, high piezo-electric, ferro-electric, pyroelectric properties. The Lead Lanthanum Zirconium Titanium Oxide (PLZT) composite [(Pb0.92La0.08)(Zr0.65Ti0.35)O3] is synthesized by simple Sol-Gel process using constituent nitrates and a solvent. The resulting powder is characterized using XRD, Particle Size Analyzer, SEM, TG-DTA, UV- Visible spectroscopy and HR-TEM. The structural parameters such as the lattice constants (a, c), X-ray density ( ), Porosity %, average crystallite size (D) have been determined using X-ray diffraction (XRD). Particle size is determined by Particle size Analyzer (PSA), Average grain size and surface morphological studies were carried out using Scanning Electron Microscopy (SEM) and d- spacing value of the material is determined using HR-TEM techniques.
