文摘
The low-temperature-fired NiCuZn ferrites with SiO2–CaO–Na2O–K2O (SCNK) glass additives are prepared by the conventional solid-state reaction method. The effects of SCNK glass additives on sintering behavior, microstructures and magnetic properties of NiCuZn ferrites are also investigated. Results show that SCNK glass additives overtly improve the densification of samples through the formation of liquid phase and grains growth promotion. The appropriate SCNK glass additives not only can noticeably increase the initial permeability (μ i ) and saturation flux density (B s ), but also can obviously reduce the remanent flux density (B r ) and coercive filed strength (H c ). However, too much glass additives will deteriorate the magnetic properties. In summary, 0.2 wt% SCNK glass added in NiCuZn ferrite shows excellent magnetic properties: μ i = 648.18 (100 kHz), B s = 166.21 mT, B r = 83.57 mT and H c = 39.38 A m−1.
