Soft magnetic powder cores are materials manufactured by pressing pure iron powder covered with insulating film into shape.
The issues to be addressed with regard to this kind of method are: (1) the pure iron used in these materials displays ductility resulting in burring and cohesion to machining tools, (2) these materials are green compacts with low binding forces between powder particles and high tendencies towards cracking and gouging, and (3) these materials possess residual pores at levels of several percent thus resulting in microscopically intermittent processing which causes heavy machining tool wear.
Soft magnetic powder cores (SMPCs) have gathered attention in recent years as materials for the iron cores described above [1].
These materials are produced by pressing pure iron powder covered with insulating film into shape.

Sulfur capacity of [Bmim]6PMo9V3O40/ACF under different concentration of O2 Generally, the desulfurization performance of activated carbon materials increases with increasing oxygen content gradually in flue gas desulfurization, but desulfurization rate will not change much when the oxygen content is higher than a certain number.
