Magnetic properties regulation and loss contribution analysis of FeSi
FeSi powder has higher resistivity and good DC bias performance due to the existence of Si element, and carbonyl iron powder (CIP) powder has fine particle size, high purity, high magnetization, and excellent filling properties for its high compressibility. Therefore, the combination of FeSi powder and CIP powder may obtain the optimizing ...
