Abstract

Abstract: Sm₂O₃ doped (Ba_0.7Ca_0.3)TiO₃-Ba(Zr_0.2Ti_0.8)O₃ (BCZT) lead-free piezoelectric ceramics were prepared by solid state synthesis method. The microstructure and electrical properties of prepared ceramics were investigated by XRD, SEM and other techniques. The results demonstrate that Sm₂O₃ doping reduces sintering temperature of BCZT lead-free piezoelectric ceramics and increases the Curie temperature Tc from 85℃ to 95℃. BCZT ceramics doped with 0.02wt%-0.1wt% Sm₂O₃ possess a typical ABO₃ type perovskite structure.With the doping of 0.02wt% Sm₂O₃, the BCZT ceramics show the optimum electrical properties, and its piezoelectric constant d33, electromechanical coupling factor k_p, mechanical quality factor Qm, dielecteic loss tanδ and relative dielectric constant ε_r reach 590 pC/N, 0.52, 43, 1.3% and 3372, respectively.

Key words: lead-free piezoelectric ceramics, Sm₂O₃, piezoelectric property, perovskite
