Abstract

The effect of particle size-grading and the packaging with various insulating agents on the properties of amorphous magnetic powder cores was investigated. Firstly, the variations of compression density, magnetic permeability, loss and DC biasing capability of amorphous magnetic powder cores were studied by changing the particle size-grading of amorphous powder. It was found that with magnetic powder of particle size-grading as 10%, 30%, 30% and 30% for particles with size in between -140~+170, -170~+200, -200~+350 and -350 ~+1000 mesh respectively, the compacting density of the amorphous magnetic powder cores increased, thereby the DC biasing capability increased, while the magnetic loss decreased. Secondly, different insulating agents were used to encapsulate the amorphous magnetic powder cores. The results show that using phosphoric acid as insulating agent can reduce the magnetic loss and improve the DC biasing capability more effectively than using water glass as insulating agent. Thirdly, low-melting glass frit not only acts as an insulator in the amorphous magnetic powder cores but also acts as a binder. Finally, the magnetic properties of the amorphous magnetic powder cores prepared by using the powder of recycled waste amorphous iron cores are not significantly different from those prepared by using the powder of the ordinary iron silicon boron alloy.
