Abstract
The low-temperature sintering behavior of (Ba0.85Ca0.15)(Zr0.10Ti0.90)O3 (BCZT) piezoelectric ceramics with Ba(Cu0.5W0.5)O3 (BCW) addition has been investigated. The addition of 0.1 wt% BCW promotes the sinterability of BCZT ceramics owing to the generation of a liquid phase, resulting in a reduction of sintering temperature from 1,540 to 1,350 °C. The piezoelectric coefficient (d 33), and the electromechanical coupling factor (kp) of the BCZT − 0.1 wt%BCW specimen sintered at 1,350 °C were 555 pC/N and 55 %, respectively, while Curie temperature (Tc) increases from 85 to 95 °C.
