Abstract

AbstractLead-free multiferroic composite ceramics of 0.7BaTiO3-0.3Ni0.7Zn0.3Fe2O4 (BT-NZF) were prepared by the solid-state combustion technique. The BT and NZF powders were calcined in the range of 1100 to 1200 °C for 4 h and 900 to 1100 °C for 2 h, respectively. Afterward, BT-NZF composite ceramics were sintered between 1100 and 1250 °C for 4 h. The effect of the firing temperature on the phase formation, microstructure, electrical, and magnetic properties of BT-NZF composite ceramics was investigated. X-ray diffraction of BT and NFZ powders showed the highest purity phase were prepared the calcination temperatures of 1100 and 1050 °C, respectively. The BT-NZF composite ceramics exhibited coexisting tetragonal perovskite and cubic spinel phases. The maximum density of 5.85 g/cm3 was obtained when sintering the composite ceramics at 1125 °C. The dielectric constant at room temperature increased with increased sintering temperature. The hysteresis loops showed leakage current in all samples. Ferromagnetic properties showed the highest Ms ∼ 24.56 emu/g measured under a magnetic field of 10,000 Oe from the sample sintered at 1150 °C.Keywords: BT-NZFcompositesmultiferroicferroelectricferromagnetic AcknowledgmentsThis project is funded by National Research Council of Thailand (NRCT): (N41A650100), Naresuan University (NU) and National Science, Research and Innovation Fund (NSRF) with Grant No. R2565B059.

固态燃烧法制备0.7 batio3 -0.3Ni 0.7 Zn 0.3 fe2o4多铁复合陶瓷

摘要采用固态燃烧法制备了0.7BaTiO3-0.3Ni0.7Zn0.3Fe2O4 (BT-NZF)无铅多铁复合陶瓷。BT和NZF粉末分别在1100 ~ 1200℃范围内煅烧4 h和900 ~ 1100℃范围内煅烧2 h。随后，将BT-NZF复合陶瓷在1100 ~ 1250℃之间烧结4 h，研究了烧结温度对BT-NZF复合陶瓷的相形成、微观结构、电学和磁性能的影响。对BT和NFZ粉末的x射线衍射结果表明，在1100℃和1050℃的煅烧温度下制备的相纯度最高。BT-NZF复合陶瓷具有四方钙钛矿相和立方尖晶石相共存的特点。在1125℃烧结时，复合陶瓷的最大密度为5.85 g/cm3。室温下介电常数随烧结温度的升高而增大。所有样品的磁滞回线均显示漏电流。在1150°C烧结的样品中，在10,000 Oe的磁场下测得的铁磁性能最高Ms ~ 24.56 emu/g。本项目由泰国国家研究委员会(NRCT)资助:(N41A650100)，那瑞山大学(NU)和国家科学研究与创新基金(NSRF)资助，批准号:R2565B059。同时感谢Kyle V.

期刊介绍： Integrated Ferroelectrics provides an international, interdisciplinary forum for electronic engineers and physicists as well as process and systems engineers, ceramicists, and chemists who are involved in research, design, development, manufacturing and utilization of integrated ferroelectric devices. Such devices unite ferroelectric films and semiconductor integrated circuit chips. The result is a new family of electronic devices, which combine the unique nonvolatile memory, pyroelectric, piezoelectric, photorefractive, radiation-hard, acoustic and/or dielectric properties of ferroelectric materials with the dynamic memory, logic and/or amplification properties and miniaturization and low-cost advantages of semiconductor i.c. technology.
