Abstract

Lead-free piezoelectric ceramics [(Ba_0.85Ca_0.15)(Ti_0.90Zr_0.10)O_3-xBiErO₃ (BCTZ-xBE)] doped with a new doping material BiErO₃ (BE) has been synthesized successfully via solid state reaction technique, and their structural, dielectric, ferroelectric, and piezoelectric properties have been investigated. A high dielectric constant with very low dielectric loss and high remnant polarization followed by a low coercive field has been obtained with the addition of x = 0.5 BE. Bulk ferroelectric hysteresis loops were obtained with a maximum polarization P_max = 26.7 μC/cm² and a saturation polarization P_s = 16.65 μC/cm² along with a coercive field of E_c ≈ 2.45 kV/cm. Results demonstrate an induced-strain increasing from ~ 0.11 to ~ 0.24 for x = 0.5, excellent piezoelectricity with d₃₃ = 560 pC/N, k_p = 56%, Q_m = 196, ε_m = 11,200 and tanδ = 0.01.
