摘要

摘要:为研制压电致动器扬声器用低温烧结陶瓷，制备了掺杂PbO、CuO和WO3的Pb(mg1 / 2w /2)O3-Pb(Ni1/3Nb2/3)O3-Pb(Zr,Ti)O3 [PMW-PNN-PZT]陶瓷，并对其显微结构、介电性能和压电性能进行了研究。当氧化钨(=WO3)添加量为0.3 wt%，烧结温度为920℃时，样品的介电常数(εr)为2275，压电常数(d33)为502 pC/N，机电耦合系数(kp)为0.644，机械品质因子(Qm)为57，均达到压电性能的最大值，适合于低温烧结多层陶瓷的触觉显示执行器等器件应用。

Physical properties of Pb(Mg1/2W1/2)O3-Pb(Ni1/3Nb2/3)O3-Pb(Zr,Ti)O3 ceramics doped with tungsten oxide for haptic display actuator

Abstract In this study, for developing the low temperature sintering ceramics for speaker using piezoelectric actuator, Pb(Mg1/2W1/2)O3-Pb(Ni1/3Nb2/3)O3-Pb(Zr,Ti)O3 [PMW-PNN-PZT] ceramics doped with PbO, CuO, and WO3 as sintering aids were manufactured, and their microstructural, dielectric, and piezoelectric properties were investigated. At 0.3 wt% tungsten oxide (=WO3) added specimen sintered at 920 °C, the maximum values of piezoelectric properties were shown, respectively: the dielectric constant (εr) of 2275, piezoelectric constant (d33) of 502 pC/N, electromechanical coupling factor (kp) of 0.644, and mechanical quality factor (Qm) of 57 were suitable for the device application such as haptic display actuator using low temperature sintering multilayer ceramics.

期刊介绍： Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
