The (BaZrTiO₃)/(BaFeO); (BZT/BF) ( = 0, 0.1, 0.5 and 1 mol%) ceramics have been prepared via a solid state reaction process. Effects of BF content on the physical, microstructural, magnetic and electrical properties have been systematically investigated. High density sintered specimens (5.65-5.74 g/cm³) are obtained for all compositions. SEM micrographs show a decrease of grain size value when BF is added. Examination of the dielectric spectra show that the two phase-transition temperatures as observed for pure BZT, merges into a single phase-transition temperature for the added-samples. The addition of BF also improves the magnetic behavior ( hysteresis loops) of BZT ceramic and resultes in slight changes in ferroelectric properties. The maximum of remanent magnetization () of 7.19 emu/g is obtained for the 1 mol% sample.
通过固态反应法制备了(BaZrTiO₃)/(BaFeO);(BZT/BF)(摩尔百分比=0、0.1、0.5和1%)陶瓷。系统研究了BF含量对其物理、微观结构、磁性和电学性能的影响。所有成分均获得了高密度烧结试样(5.65 - 5.74 g/cm³)。扫描电子显微镜图像显示,添加BF后晶粒尺寸值减小。介电谱研究表明,纯BZT中观察到的两个相变温度,在添加样品中合并为一个单一的相变温度。BF的添加还改善了BZT陶瓷的磁性能(磁滞回线),并导致铁电性能略有变化。1 mol%样品的剩余磁化强度()最大值为7.19 emu/g。
