研制了一种新型的添加Pb（Mn1／3Sb2／3）O3、碱土金属CaCO3、Bi2O3、NiO的改性钛酸铅压电陶瓷材料．该材料具有高压电活性、大压电各向异性、低介电常数及小的机械品质因素．实验确定其典型配方为Pb0．80Ca0．20［（Mn1／3Sb2／3）0．05Ti0．95］O3＋0．5wt％NiO＋1wt％Bi2O3；在优化后的制备工艺条件下，其主要性能参数为：εT33/ε0＝160, d33＝70×10-12C·N-1；Kt＝60．0；Hp≈0，Qm＝43，Nt＝2004Hz·m．
A new modified PbTiO3 piezoelectric ceramic material added with Pb(Mn1/3Sn2/3)O3 , CaCO3,Bi2O3, NiO was prepared. The modified material has high piezeoelectric activities, large piezoelectric anisotropy as well as low dielectric constant, and low mechanical quality factors. The typical composition of this material obtained from experiments is Pb0.80Ca0.20[(Mn1/3Sb2/3)0.05Ti0.95]O3+0.5wt% NiO+1wt%Bi2O3. Under the optimized preparation technique, its main performance are as follows. εT33/ε0＝160, d33=70×10-12C·N-1；Kt＝60．0；Hp≈0，Qm＝43，Nt＝2004Hz·m．
