The crystal structure and morphology of the composites were examined with X-ray diffraction and scanning and transmission electron microscopes. Scanning electron micrographs showed structural homogeneity. Dielectric and piezoelectric properties were studied as a function of x to characterize electrical properties of composites. The presence of two trivalent ions (La3+ and Bi3+) in x resulted in high dielectric and piezoelectric properties. The possible mechanisms of mechanical activation technique of (1−x)PLZT-xPBLBiN nanoceramic composite system are discussed. The optimum dielectric and piezoelectric properties were found in x=0.6 in (1−x)PLZT-xPBLBiN nanoceramic composite system which could be ideal for electromechanical and energy harvesting applications.
