Abstract
The effects of B 2O 3 doping on densification, ferroelectric, and piezoelectric properties of Ba(Zr 0.07Ti 0.93)O 3(BZT) ceramics were investigated. The addition of B 2O 3 to the ceramics lowered the sintering temperature by ∼200 °C as well as changed their microstructures. Higher B 2O 3 concentration caused a decrease in remanent polarization and coercive field, while the piezoelectric coefficient d 33 remained at a high value of 291 pC/N for the ceramic sample with 2 wt.% B 2O 3. The relationship between piezoelectric properties and ferroelectric constant was examined.
