摘要

本研究描述了通过固态反应合成的0.1Pb[Fe1/2Nb1/2]O3-0.9Pb[ZrxTi（1–x）]O3（x=0.49-0.55）陶瓷的微观结构、晶体结构、介电和压电行为。将组合物在1180℃下烧结120分钟。通过微观结构分析，可以看到致密均匀的微观结构。XRD图谱证实，在0.51≤x≤0.53的组成中，四方和菱形钙钛矿相共存。0.51≤x≤0.53的组分产生了最佳的性能值，即介电常数（εrr）为1150，压电系数（d31）为95x10–12 C/N，压电电压常数（g31）为70x10–3 mV/N，耦合因子（kp）值为0.67。结果表明，该材料组合物可适用于功率采集和传感器应用。图形摘要

Effect of Zr/Ti Ratio on Piezoelectric and Dielectric Propertiesof 0.1Pb[Fe1/2Nb1/2]O3-0.9Pb[ZrxTi(1–x)]O30 Ceramics

This study describes the microstructure, crystal structure, dielectric and piezoelectric behavior of 0.1Pb[Fe1/2Nb1/2]O3-0.9Pb[ZrxTi(1–x)]O3 (x = 0.49-0.55) ceramics synthesized by solid-state reaction. Compositions were sintered at 1180oC for 120 min. Dense and uniform microstructure was seen through microstructural analysis. XRD pattern confirmed the co-existence of tetragonal and rhombohedral perovskite phases in these compositions where 0.51 ≤ x ≤ 0.53. Compositions with 0.51 ≤ x ≤ 0.53 resulted in the optimum values of properties, viz. dielectric constant (ϵrr) of 1150, piezoelectric coefficient (d31 ) of 95x10–12 C/N, piezoelectric voltage constant (g31 ) of 70x10–3 mV/N and the coupling factor (kp ) value of 0.67. Results indicated that this material composition could be suitable for power harvesting and sensor applications. GRAPHICAL ABSTRACT
