Effect of magnetic properties in FeSi soft magnetic composites by low melting glass powder as adhesive and insulating agent.

Ni, J. L.; Zhu, S. J.; Feng, S. J.; Kan, X. C.; Liu, X. S.

FeSi/1wt% glass soft magnetic composites are prepared by mechanically mixing, compacting, and annealing, their morphology is examined by SEM, and their magnetic properties are measured by MPMS and B-H analyzer. The morphology of SEM shows that when the annealing temperature is higher than the melting point of the glass, the glass particles between the FeSi balls are deformed into flakes. The sample has higher saturation magnetization and lower power loss. The magnetic permeability and mechanical strength of the sample increase with the increase of annealing temperature, but the best power loss characteristics emerge at annealing temperature of 400 °C.
