Iron-based soft magnetic composites (SMCs) were prepared by two-step ball milling with sodium silicate and ferroferric oxide. The presence of the precoated silicate layer has increased the resistivity of the powder surface, which also improved the agglomeration of ferroferric oxide. The addition of magnetic ferroferric oxide improves the dilution effect. Combining the advantages of both sodium silicate and ferroferric oxide, the prepared soft magnetic composite material has excellent performance. After annealing at 400 C, the core loss is 214.5 W Kg⁻¹ (1 T, 1000 Hz), and the saturation magnetic induction is 1.33 T.

交流—两级球磨法制备Fe / Na ₂ SiO ₃ / Fe ₃ O ₄软磁性复合材料的磁性能

铁基软磁复合材料（SMCs）是通过两步球磨与硅酸钠和三氧化二铁制备的。预涂硅酸盐层的存在增加了粉末表面的电阻率，这也改善了三氧化二铁的团聚。磁性三氧化二铁的添加改善了稀释效果。结合硅酸钠和三氧化二铁的优点，制备的软磁复合材料具有优异的性能。在400℃下退火后，铁损为214.5W Kg ^-1（1T，1000Hz），饱和磁感应强度为1.33T。
