Grain size dependence of the microstructures and functional properties of (Ba0.85 Ca0.15–x Cex) (Zr0.1 Ti0.9) O3 lead-free piezoelectric ceramics

Journal of Asian Ceramic Societies, 2018
By the solid-state reaction route, (Ba0.85Ca0.15-x Cex) (Zr0.1Ti0.9) O3 (BCCeZT) lead-free piezoelectric ceramics were prepared. The powder was processed at 1250 ºC for 2 h, and compacted green bodies were then sintered at various sintering temperatures.
