Abstract
The influence of glass additives on the densification, microstructural evolution and magnetic properties of NiCuZn ferrites were investigated. Two glass systems including PbO·SiO2 and PbO·B2O3 were used to reduce the sintering temperature of a NiCuZn ferrite. The PbO·SiO2 glass system was shown to be an effective additive to obstruct the grain boundary movement and prevent the abnormal grain growth. In addition, it significantly lowers the sintering temperature of the ferrite. Ferrites sintered with PbO·SiO2 have higher resistivity, higher Q and higher Hc compared with those of PbO·B2O3 systems. These results also indicated that the ratio of modifier to glass-former did not significantly change the densification behavior, microstructural evolution and magnetic properties of the NiCuZn ferrite.
