| 2 | Enhanced ferroelectric and piezoelectric characteristics in Ca-substituted BaTi_(0.88)Zr_(0.12)O_(3)ceramics显示文摘In this work,Ba1−xCaxTi_(0.88)Zr_(0.12)O_(3)(x=0.00-0.25)ceramics were prepared by a solid-state reaction method,and the variation of dielectric,ferroelectric and piezoelectric characteristics has been investigated together with the structure evolution.The crystal structure varies from rhombohedral to tetragonal at room-temperature and the morphotropic phase boundary(MPB)is determined around x=0.10,where the significantly enhanced ferroelectric and piezoelectric properties are achieved.With the increase of Ca content,the system gradually evolves into a relaxor ferroelectric.This work provides useful guidance for future research on lead-free piezoelectric materials. | S.B.Chen S.Y.Wu X.M.Chen | 2022 | Journal of Advanced Dielectrics2022，12，3： | 0 |
