The piezoelectric Lanthanum Lead zirconate titanate (PLZT) based ceramics with a composition of La0.6Pb0.94 (Zr0.52Ti0.48)O3 were studied using sol-gel auto-compulsion method. The specimens were fabricated and studied to understand the effect of ph7 adjustment on the microstructure, dielectric and the ultrasonic mechanical properties. The material was characterized for DSC/TGA and TEM studies. A polycrystalline single phase of PLZT with tetragonal structure was obtained, for the powder calcined at 600 for 3 h and 850 °C for 3 h. The electrical properties of the prepared ceramics were investigated as a function of the frequency using impedance analyzer. The remnant polarization (Pr) and coercive electric field (Ec) were calculated from the ferroelectric loop by Sawyer-Tower circuit.
