| 摘 要： | 以氯化铁（FeCl3·6H2O）和氨水（NH3·H2O）为原料,以十六烷基三甲基溴化铵（CTAB）为表面活性剂,采用沉淀法制备了氧化铁磁性微球.所得样品用XRD、SEM及SQUID-VSM等手段进行了表征.结果表明,所得氧化铁磁性微球为斜方六面体结构,其粒径大小在0.5-1.5μm范围,其剩余磁感应强度为0.06emu/g,矫顽力为1700Oe,表现出一定的铁磁性.

| Abstract: | Monodispersed magnetic hematite microsperses were prepared by the homogenous precipitation method using FeCla · 6HaO and NHa · H2O as main raw materials. The structures of magnetic hematite microsperses are characterized through X ray diffraction （XRD）,scanning electron microscope （SEM）and super-conducting quantum interference device magnetometer （SQUID）. The results indicated that the diameter of magnetic hematite microsperses is 0. 5-1. 5μm. The saturation magnetization and the coercivity of the resulting products are 0. 06 emu/g and 1700Oe,respectively. |
