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