On preparation of high permeability Mn-Zn ferrite

With the development of electronic information technology, the electronic equipment are required to be smaller, lighter and more reliable, which puts forwards a higher request to the electronic elements with ferrite materials. In this dissertation, high permittivity MnZn ferrite are fabricated by solid state reaction method with Fe2O3,MnOand ZnO as starting raw material. The effects of formulation and sintering technique on the properties of the samples were studied. Finally, the results showed that: the best formula of high permeability Mn-Zn ferrite is Fe2O3: MnO: ZnO = 51:25:24mol%;the best sintering temperature is 1360 degrees C.
