  • POWDER FOR DUST CORE, DUST CORE MADE OF THE POWDER FOR DUST CORE BY POWDER COMPACTION, AND METHOD OF PRODUCING THE POWDER FOR DUT CORE
    Publication number: 20120012777
    Abstract: A powder for dust core including a soft magnetic metal powder and a silicon impregnated layer made of silicon concentrated in a surface layer of the soft magnetic metal powder, in which a silicon dioxide powder is diffusion-bonded to a surface of the silicon impregnated layer to form a diffusion-bonded part while a part of the silicon dioxide powder is impregnated and diffused in the silicon impregnated layer and the other part of the same protrudes from the surface of the silicon impregnated layer. The diffusion-bonded part creates a gap with respect to another powder for dust core, thereby providing increased specific resistance.
