摘要
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．
The piezoelectric properties of xPb(Ni1/3Nb2/3)O3-(1-x)Pb(ZrδTi1-δ)O3(0.2<x<0 .6, 0.2< δ <0.5) ternary solid solutions were investigated. The results showed that the high piezoelectric-activitycompositions were near the morphotropic phase boundary(MPB). The highest value of the piezoelectric constant d31 was 260 x 10-12C / N. The effect of structural phase transition between FR and FT on piezoelectric properties was also discussed.
