| 摘 要： | 采用预合成及掺杂适量MnO2等工艺制备了钙钛矿结构为主的压电陶瓷材料Pb（Mn1/3Sb2/3)x(Zn1/3Nb2/3)y(Zr0.535Ti0.465)1-x-yO3，此材料具有机电耦合系数高、介质损耗小、介电常数与机械品质因数适中的特点。引入MnO3使其成为单一的钙态矿结构，并且提高了材料的介电与压电性能。

| Abstract: | Pb(Mn 1/3 Sb 2/3 ) x (Zn 1/3 Nb 2/3 ) y (Zr 0.535 Ti 0.465 ) 1 -x-y O 3 piezoelectric ceramics with mainly perovskite structure were prepared by multi presinter and MnO 2 doping.The materials have high electromechanical coupling coefficients and low dielectric loss as well as suitability between dielectric constant and mechanical quality factor.A single perovskite structure was obtained with MnO 2 addition,and the piezoelectric and dielectric properties of material were improved. |
