|Abstract:||Effects of the sintering temperature on the microstructure and electrical properties of (Ba 0.90Ca 0.10)(Ti 0.85Zr 0.15)O 3 (BCTZ) lead-free piezoelectric ceramics have been studied, where these ceramics were prepared by the conventional oxide-mixed method at varied sintering temperatures from 1300 °C to 1500 °C. These BCTZ ceramics exhibits a phase transition from a rhombohedral phase to the coexistence of rhombohedral and tetragonal phases with an increase of sintering temperature. With an increase of sintering temperature, their relative density and average grain size gradually increase, and electrical properties are improved greatly. These BCTZ ceramics sintered at ∼1440 °C have optimum electrical properties: d 33 ∼ 442 pC/N and k p ∼ 48.9%, making it a promising material for lead-free piezoelectric ceramics. © 2012 Elsevier Ltd.
