Abstract
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.
