摘要
In order to shift the tricritical point to room temperature, Ba0.85Ca0.15Ti0.90Zr0.10O3 (BCTZ) ceramics were prepared by normal sintering with the addition of ZnO. The sintering behavior of BCTZ ceramics is also improved by using ZnO as a sintering aid. The room-temperature tricritical point results in improved electrical properties of ZnO-modified BCTZ ceramics. BCTZ ceramic with 0.06 mol.% ZnO demonstrates good piezoelectric properties: d33 ∼ 521 pC N−1 and kp ∼ 47.8%.
