With high pure starting materials, the precursor ScTaO_4 with wolframite structure was synthesized firstly, then by mixing the precursor with the other oxides, the (1-x)PST-xPb(Zr_ 0.52Ti_ 0.48O_3) relaxor ferroelectrics ceramics (abbr. as PSTZT) were prepared by sintering from 1200 to 1300℃. The XRD analysis results demonstrated that the PSTZT ceramics were with pure perovskite structure. The temperature dependence of permittivity and dielectric loss of PSTZT ceramics were investigated in detail, which indicated that PSTZT ceramics showed a typical diffusive phase transition. The dielectric constant ε_r and the piezoelectric constant d_ 33 of PSTZT ceramics increase with increase of the concentration of PZT and the sintering temperature. The impedance analysis showed that no clear crystal boundary phase existed in PSTZT ceramics. The piezoelectric properties dependent on the concentration of doped PZT in PSTZT ceramics were also investigated and discussed.

利用高纯原料,先合成钨锰矿型ScTaO4先驱体,再与其它氧化物混合成形后,在1200~1300℃下烧结制备了(1x)PSTxPZT(简写为PSTZT)弛豫铁电陶瓷。X射线衍射测试表明PSTZT陶瓷为钙钛矿相结构。随烧结温度和PZT掺入量的不同,PSTZT陶瓷中钙钛矿相的含量有所变化。PSTZT铁电陶瓷具有明显的弥散型介电响应特征,其介电系数εr,压电常数d33等随PZT掺入量增大而呈现上升趋势,随烧结温度的升高而有所增加。阻抗分析表明PSTZT陶瓷没有明显的晶界相存在。讨论了PZT掺杂对PSTZT陶瓷性能影响的机理。
