7. 再者将四氧化三铁磁性流体吸附凝集於黏土水溶液中来形成具有磁性的黏土,由震荡样品测磁仪分析其矫顽磁力皆小於30 Oe,表示几乎无任何的磁滞现象,故属於具有超顺磁性的磁性黏土,且随著四氧化三铁的添加,实际氧化铁的饱和磁化量为49.62~72.14 emu/g Fe3O4,皆比纯四氧化三铁磁粉Ms = 42.43 emu/g 来得高;由XRD结果可知随著四氧化三铁含量的增加,其2θ=1.5°~10°之间的绕射峰会渐向左移且渐消失,意味著四氧化三铁与黏土之间的分散性良好,可有效破坏黏土层间的作用力。
Besides, the Fe3O4 magnetic fluid was employed to be absorbed on clay surface to form magnetic clay. The magnetic clay was measured by Vibration Sample Magnetometer and gives the coercive force below 30 Oe with no apparent indication of hysteresis loop that bears the characteristic of superparamagnetic materials. With the increased addition of Fe3O4 in clay, the saturation magnetization of iron oxide is increased from 49.62 to 72.14 emu/g Fe3O4, this is higher than that of pure Fe3O4 which has Ms of 42.43 emu/g. XRD results showed that the diffraction peak between 2θ=1.5°~ 8°is shifted to left and vanish gradually with an increased content of Fe3O4 in clay. This means a good dispersion achieved between Fe3O4 nanoparticles and clay platlets due to the electrostatic attraction force.
