摘要
介绍利用自蔓延高温合成技术合成SrFe_(12)O_(19)的工艺过程以及对合成产物的分析。采用X射线衍射(XRD)分析产物的物相;采用透射电子显微镜(TEM)观察其微观结构、晶粒形状及尺寸;采用振动样品磁强计(VSM)测试粉末磁性能,Hc为2559.08奥,4πMs为3468.3高斯。试验结果表明:采用自蔓延高温合成技术可合成高纯度的SrFe_(12)O_(19),具有良好稳定的磁性能。
The process of Self-propagating High-temperature Synthesizing (SHS) SrFe12O19 composite was emphatically reported in this paper. The constituent phases, microstructure and magnetic properties of the composites were investigated by means of X-ray diffraction (XRD), transmission electron micrograph (TEM), vibrating sample magnetometer (VSM) repectively. The results show the SrFe12O19 cumposite using SHS was highly pure and possess good magnetic properties.
