摘要

研究了含BaFe12O19、BaFe11.8Al0.2O19、bazn0.2 zr0.2 fe11.60 o19和bazn0.2 zr0.2 al0.2 fe11.40 o19的磁铅石结构的未取代和络合取代钡铁氧体。重点研究了它们的相组成和居里温度区间内的磁相变。揭示了铁氧体晶格体积随取代阳离子尺寸的变化规律。在磁场中同时进行热分析时,观察到样品重量的仪器变化与其居里温区热容的变化之间存在相关性。结果表明,随着铁原子取代元素含量的增加,磁性相变温度范围增大,居里温度减小。结果表明,热分析可以有效地分离bafe12o19 - bazn0.2 zr0.2 al0.2 fe11.40 o19复合粉末混合物中的相,由于这两种铁氧体相的晶格参数差异很小,因此无法使用X射线衍射,从而导致它们在XRD图中峰重叠。本研究结果强调了在多组分磁性材料相组成检测中使用同步热分析的重要性。

Application of X-ray diffractometry and simultaneous thermal analysis for studying the phase composition of barium ferrites

Unsubstituted and complex substituted barium ferrites of a magnetoplumbite structure of the following compositions: BaFe12O19, BaFe11.8Al0.2O19, BaZn0.2Zr0.2Fe11.6O19 and BaZn0.2Zr0.2Al0.2Fe11.4O19 are studied. The main focus is on their phase compositions and magnetic phase transitions within the Curie temperature interval. The common patterns of variation in the ferrite crystal lattice volume as a function of the substituting cation sizes are revealed. During a simultaneous thermal analysis in the magnetic field, a correlation is observed between the instrumental variation of the sample weight and the changes of their heat capacity in the Curie temperature region. It is found out that the temperature range of the magnetic phase transition increases with the increasing content of the elements substituting iron atoms, while the Curie temperature decreases. It is shown that a thermal analysis allows effectively separating the phases in the mixture of composite powders of BaFe12O19—BaZn0.2Zr0.2Al0.2Fe11.4O19, not possible using X‑ray diffraction due to very small differences in the crystal lattice parameters of these two ferrite phases, causing an overlapping of their peaks in the XRD pattern. The results of this study emphasize the importance of using the simultaneous thermal analysis during the examination of phase compositions of multicomponent magnetic materials.
