Abstract: The effects of B2O3doping on densification, ferroelectric, and piezoelectric properties of Ba(Zr0.07Ti0.93)O3(BZT) ceramics were investigated. The addition of B2O3to the ceramics lowered the sintering temperature by ∼200 °C as well as changed their microstructures. Higher B2O3concentration caused a decrease in remanent polarization and coercive field, while the piezoelectric coefficient d33remained at a high value of 291 pC/N for the ceramic sample with 2 wt.% B2O3. The relationship between piezoelectric properties and ferroelectric constant was examined. © 2009 Elsevier B.V. All rights reserved.
