Abstract The Aurivillius phase-based composition bearing chemical formula Bi4Pb2Zr2TiFeNbO18 (termed as BPZTFNO) was synthesized by a solid-state method. The structural analysis as obtained from the X-ray pattern has depicted an orthorhombic phase. The various size and morphology of grains are distributed throughout the natural surface as revealed from microstructure analysis. The dielectric and electrical study of the BPZTFNO is taken at a various sweep of frequency (1 kHz–1 MHz) and temperatures (25–400 °C). The ferroelectric-paraelectric phase transition is well illustrated from the temperature-dependent dielectric constant. The complex impedance analysis suggests the association of grain effect. The relaxation of non-Debye nature is shown in the impedance study. The formed sample is subjected to an electric field and further its excitation performance is examined suggesting its possible usage in devices.

Aurivilius 氧化物的介电、阻抗和激发性能：Bi4Pb2Zr2TiFeNbO18

摘要 通过固态方法合成了化学式为Bi4Pb2Zr2TiFeNbO18 的Aurivilius 相基组合物（称为BPZTFNO）。从 X 射线图案获得的结构分析描述了正交相。从微观结构分析中可以看出，晶粒的各种尺寸和形态分布在整个天然表面。BPZTFNO 的介电和电学研究是在不同的频率扫描 (1 kHz–1 MHz) 和温度 (25–400 °C) 下进行的。铁电-顺电相变从与温度相关的介电常数中得到了很好的说明。复阻抗分析表明了颗粒效应的关联。阻抗研究显示了非德拜性质的松弛。
