COMPOSITE SOFT MAGNETIC MATERIAL AND PRODUCTION METHOD THEREFOR |
摘要 |
<p>Provided are a composite soft magnetic material, having favorable DC bias characteristics and high specific resistance, and a production method therefor. An inorganic insulative powder (3) and a coated powder obtained by coating a soft magnetic powder (1) that is coated with an insulative film (4) with a silicone resin (2) are uniformly mixed, and the resultant mixture is molded and fired. By uniformly mixing the inorganic insulative powder (3) and the coated powder obtained by coating the soft magnetic powder that is coated with the insulative film (4) with the silicone resin (2), rupture of the insulative film due to the inorganic insulative material when molding pressed powder is prevented. By uniformly dispersing the inorganic insulative material while high specific resistance is maintained, the gap between molded soft magnetic powder particles is uniformly maintained. As a result, a composite soft magnetic material is provided having high specific resistance and favorable DC bias characteristics.</p> |
