Abstract

Sintering behavior and magnetic properties of NiCuZn ferrites with different amount of Nb2O5 and MoO3 additions were investigated. It was found that Nb2O5 and MoO3 additives could improve densification and promote uniform grain growth. The appropriate Nb2O5 and MoO3 additions not only efficiently increase the initial permeability (μi) and saturation flux density (Bs), but also noticeably reduce the remanent flux density (Br) and coercive filed strength (Hc) of the NiCuZn ferrites sintered at 925 °C. By contrast, the NiCuZn ferrites with 0.2 wt% Nb2O5 and 0.3 wt% MoO3 additions showed excellent magnetic properties: μi=1097.88 at 100 kHz, Bs=160.81 mT, Br=63.55 mT and Hc=26.6 A·m-1.
