| Abstract: | The piezoelectric properties of PZN-PT-BT ferroelectric ceramic are discussed in this paper. The results show that d 33 and kp are maximum in the vicinity of the morphotropic phase boundary. The physical mechanism and the effect of its structure on piezoelectric properties are carefully analysed. |
