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。
The acicular α-FeOOH was prepared under the action of permanent magnetic field and the character of the article was studied by TEM, XRD and DTA. The results show that the crystallinity of α-FeOOH is obviously improved, the particle size distribution is uniform and the axial ratio is easier to control.
