摘要
本文详细研究了ＰＺＮ—ＰＴ—ＢＴ系铁电陶瓷在相界附近的压电性能，结果表明，在相界附近ｄ３３和ｋｐ出现极大值，并详细分析了其物理机制及结构对压电性能的影响．
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.
