Abstract

Abstract In this work, in order to develop piezoelectric ceramics sintered at low temperature with high piezoelectric d31 coefficient, Pb(Mg1/2W1/2)0.03(Ni1/3Nb2/3)0.09(Zr0.5Ti0.5)0.88O3 ceramics were fabricated as a function of the amount of Fe2O3 addition using a conventional mixed oxide method. The microstructure, dielectric and piezoelectric properties were systematically investigated as a function of amount of Fe2O3 addition. At the sintering temperature of 920 °C, the excellent values of density = 7.94 (g/cm3), piezoelectric coefficient (d31) = 246 pC/N, planar electromechanical coupling coefficient (kp) = 0.69, mechanical quality factor (Qm) = 213, dielectric constant (εr) = 2,682 and high Curie temperature =366 °C were obtained from the ceramics doped with 0.3 wt% Fe2O3, respectively.

fe2o3掺杂PMW-PNN-PZT陶瓷具有优异的压电性能和高Tc
摘要为了制备高压电d31系数的低温烧结压电陶瓷,采用传统的混合氧化物法,制备了以Fe2O3添加量为函数的Pb(mg1 / 2w /2)0.03(Ni1/3Nb2/3)0.09(Zr0.5Ti0.5)0.88O3陶瓷。系统地研究了Fe2O3添加量对材料微观结构、介电和压电性能的影响。在烧结温度为920℃时,掺量为0.3 wt% Fe2O3的陶瓷分别获得了密度7.94 (g/cm3)、压电系数(d31) = 246 pC/N、平面机电耦合系数(kp) = 0.69、机械品质因子(Qm) = 213、介电常数(εr) = 2682和高居里温度366℃的优异值。

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.
