Abstract  Appropriate addition of CuO/V2O5 and the reduction of the granularity of the raw materials particle decrease the sintering temperature of NiZn ferrite from 1200 ??C to 930 ??C. Furthermore, the magnetic properties of the NiZn ferrite prepared at low temperature of 930 ??C is superior to that of the NiZn ferrite prepared by sintering at high temperature of 1200 ??C because the microstructure of the NiZn ferrite sintered at 930 ??C is more uniform and compact than that of the NiZn ferrite sintered at 1200 ??C. The high permeability of 1700 and relative loss coefficient tan|?/|ìi of 9.0?á10−6 at 100 kHz was achieved in the (Ni0.17Zn0.63Cu0.20)Fe1.915O4 ferrite.

Key words： Silicon Materials NiZn ferrite      Low temperature      High permeability      Low loss
