Structure Evolution and Performance of Fe-Si Core Used in Power Inductors of Smart Meters
Fe-Si cores with a CoO-SiOx-Co composite coating layer were prepared by sintering Fe-6.5wt.%Si/Co3O4 composite powders. The effects of Co3O4 coating content and structural evolution mechanism on magnetic properties of the Fe-Si cores were systematically studied. The results indicate that the high temperature during hot pressing sintering promotes solid-state interface reactions between Co3O4 coating and Si atoms from the Fe-6.5wt.%Si magnetic powder, resulting in the formation of electrical insulation phase SiOx and ferromagnetic phase Co. The formed CoO-SiOx-Co composite coating layer can effectively weaken the eddy current effect and magnetic dilution effect. When the Co3O4 coating content increases, the saturation magnetization of Fe-Si core decreases but still maintains a high value. And the magnetic loss shows a trend of first decreasing and then increasing. When the Co3O4 coating content is 5.0 wt.%, the Fe-Si core exhibits relatively superior magnetic properties, such as high saturation magnetization (192.9 emu/g), high permeability (98), and low magnetic loss (343.3 kW/m3, 0.02 T/50 kHz).
期刊介绍：
The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications.
Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field.
A journal of The Minerals, Metals & Materials Society.
