Abstract
Abstract Pr 2 O 3 -doped Ba 0.85 Ca 0.15 Ti 0.90 Zr 0.10 O 3 (BCTZ- x Pr) ceramics were prepared by the conventional solid-state method. A tetragonal phase is only observed in these ceramics, and the introduction of Pr 2 O 3 decreases their sintering temperature without affecting negatively the piezoelectric constant. Enhanced ferroelectric properties were obtained in these BCTZ- x Pr ceramics. The ceramic with x =0.06 wt% exhibits a good electrical behavior of d 33 ∼460 pC/N, k p ∼47.6%, e r ∼4638, and tan δ ∼0.015 when sintered at a low temperature of ∼1400 °C. As a result, the BCTZ- x Pr ceramic is a promising candidate for lead-free piezoelectric ceramics.
