超细铁黄在磁场作用下结晶行为的研究

Study on the Crystal Behaviour of Ultrafine Iron Yellow Powder Affected by Magnetic Field

在永磁磁场作用下制备针状α-FeOOH并通过TEM,XRD,DTA等表征手段,研究了文题内容。结果表明,所得α-FeOOH结晶完整性有明显好转,粒度分布均匀,轴比更容易控制。

Needle-like α-FeOOH is prepared under the action of permanent magnetic field. The main materials of the paper are characterized by TEM. XRD. DTA etc. The results show that the perfection of α-FeOOH crystal obtained is improvd obviously, The size of particles, is well distributed and the ratio of axis is controled easily.
