Abstract

Lead-free (Ba_0.99Ca_0.01)(Ti_0.98Zr_0.02)O₃ (BCZT)+x mol% Tb (x=0-0.6) ceramics were prepared using a solid-state reaction technique. Phase structure, dielectric constant, ferroelectricity and temperature-dependent piezoelectric coefficient were explored. With an increasing Tb content, the orthorhombic-tetragonal phase transition temperature (T_O-T) shifted to lower temperature while its Curie temperature (T_c) remained at 130 °C. The temperature stability of piezoelectric coefficient (d₃₃) could be enhanced from 30 to 120 °C in Tb-doped BCZT ceramics. A piezoelectric coefficient of d₃₃=542 pm/V was obtained at x=0.2 with low temperature-dependent degradation from 30 to 120 °C. The results indicated that Tb-doped BCZT ceramics could be a promising candidate for commercial purposes.
