The adopted preparation method comprises the following steps: paper fibre or porous organism is used as a hard template; CoFeFe-LDH is synthesized in the surface and holes of the hard template and roasted to prepare the magnetic cobalt iron ferrite; as the function for fixing the houghite position is produced by the obstruction and adsorption of the hard template, the occurrence of the sintering phenomenon is greatly avoided, thereby preparing the magnetic cobalt iron ferrite with a consistent shape and even granularity.

所采用的制备方法是以纸纤维或多空有机物为硬模板、在硬模板表面及孔内合成Co 2 Fe 2 Fe 3 -LDH，再经焙烧得到磁性钴铁铁氧体，由于硬模板的阻隔和吸附而产生的水滑石位置固定作用，极大地避免了烧结现象发生；从而得到形状一致、粒度均匀的钴铁铁氧体。

Under the sametemperature, with the increase of the quantity of the additions, the density hasincreased, and the variation of the mechanical properties of these materialsdepended on the density and the quantities of the second-phase particle and intercrystalline phase of these materials.
