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 tanδ/μi of 9.0×10−6 at 100 kHz was achieved in the (Ni0.17Zn0.63Cu0.20)Fe1.915O4 ferrite.
