This invention relates to method for preparing spinel-type ferrite at mild condition.

本发明提供了一种温和条件下制备尖晶石型铁氧体的方法。

As the result,the research on the relationship between the properties of spinel ferrites and the corresponding preparation processes is quite important.

因此，研究尖晶石铁氧体的制备过程对其性质的影响就显得十分重要。

The performance of spinel ferrite is found to be related to their stoichiometric compositions and microstructures,which are predestined by the preparation processes.

尖晶石铁氧体的性质与其化学配比和微结构有着密切的联系，而这些又与其制备过程密不可分。

Metallic nickel powder is taken as a matrix; a chemical method is adopted to prepare a product required by cladding ferrites on the surface of the nickel powder; the mass ratio of the ferrites to the nickel compound powder is between 1 to 5 and 1 to 0.01; the grain diameter of the nickel powder is 0.5 to 5 microns; the ferrites are ferrites of spinel type or ferrites of magneto plumbite type.

以金属镍粉作为基体，采用化学方法在镍粉表面包覆铁氧体层制得所需产品，铁氧体与镍复合粉体的质量比为1∶5～1∶0.01，镍粉粒径为0.5～5μm，铁氧体为尖晶石型铁氧体或磁铅石型铁氧体。

These systematic studies can contribute to the study of the applications of NiZn ferrite.Meanwhile,the research methods employed in this thesis can also be applied to other kind of similar ferrites and even other ceramics.

以上系统的工作，对NiZn铁氧体的实际应用具有一定的参考和借鉴价值，同时本论文中的研究方法对其它尖晶石铁氧体的研究也具有一定的指导意义。
