对Ｐｂ（Ｎｉ１／３Ｎｂ２／３Ｏ３－ＰｂＺｒＯ３－ＰｂＴｉＯ３，即ｘＰｂ（Ｎｉ１／３Ｎｂ２／３）Ｏ３－（１－ｘ）Ｐｂ（ＺｒδＴｉ１－δ）Ｏ３（０．２≤ｘ≤０．６，０．２≤δ≤０．５）三元系固溶体的压电性能进行了研究，结果表明材料压电活性较高的配方位于准同型相界（ＭＰＢ）附近，压电常数ｄ３１值可达２６０×１０－１２Ｃ／Ｎ．讨论了结构相变对压电性能的影响．
Pb (Ni1 / 3Nb2 / 3O3-PbZrO3-PbTiO3, ie, xPb (Ni1 / 3Nb2 / 3) O3- (1-x) Pb (ZrδTi1-δ) O3 (0.2 ≦ x ≦ 0.6, 0.2 ≤δ≤0.5) was investigated. The results show that the material with higher piezoelectricity is near the MPB and the piezoelectric constant d31 is up to 260 × 10- 12C / N. The influence of phase transformation on the piezoelectric properties was discussed.
