Abstrakt: This article studies the microstructure and piezoelectric properties of low sintering temperature lead-free ceramics -doped with ZnO nanoparticles (noted as 0.48BZT- y, y is content of ZnO in wt%, y =0.00, 0.05, 0.10, 0.15, 0.20 and 0.25). The obtained results of Raman scattering and dielectric measurements have confirmed that has occupied B site, to cause a deformation in the ABO3-type lattice of the 0.48BZT- y compounds. The 0.15 wt% ZnO-doped ceramic sintered at 1350C exhibited excellent piezoelectric parameters: , , , and . The obtained results indicate that the high-quality lead-free BZT-BCT ceramic could be successfully synthesized at a low sintering temperature of 1350C by doping an appropriated amount of ZnO.
