Description
(1)イオウ原子(S)を含むFe−Si−M系軟磁性合金(但し、MはFeより酸化し易い金属元素である。)を含む磁性粒子どうしが互いに酸化膜を介して結合してなる磁性体。
(2)0.004〜0.012wt%のSを含有する(1)の磁性体。
(3)1.5〜7.5wt%のSi、2〜8wt%の金属M、S、Fe、酸素原子及び不可避不純物のみからなる(1)又は(2)の磁性体。
(4)見かけ密度が5.7〜7.2g/cm3である(1)〜(3)の磁性体。
(5)金属MがCr又はAlである(1)〜(4)の磁性体。
(6)前記磁性粒子がアトマイズ法で製造されてなるものである(1)〜(5)の磁性体。
(7)前記磁性粒子がアトマイズ法で製造され、前記アトマイズ法による製造の際にSが添加されてなるものである(1)〜(5)の磁性体。
(8)前記酸化膜が磁性粒子自体の酸化物を含み、前記酸化膜を介する結合は熱処理によりなされてなるものである(1)〜(7)の磁性体。
(9)(1)〜(8)の磁性体を含有する磁心を備える電子部品。
また、磁性粒子は組成の異なる磁性粒子や粒度分布の異なる磁性粒子の混合粉を用いる方法も挙げられる。
熱処理は酸化雰囲気下で行うことが好ましい。より具体的には、加熱中の酸素濃度は好ましくは1%以上であり、これにより、酸化膜を介する結合部22が生成しやすくなる。酸素濃度の上限は特に定められるものではないが、製造コスト等を考慮して空気中の酸素濃度(約21%)を挙げることができる。加熱温度については、磁性粒子11自体が酸化して酸化膜12を生成し、その酸化膜12を介して結合を生成させやすくする観点からは好ましくは600〜800℃である。酸化膜12を介する結合部22を生成させやすくする観点からは、加熱時間は好ましくは0.5〜3時間である。
アトマイズ法にて磁性粒子を調製した。アトマイズ法においてはFe、Cr(フェロクロム)、Si、Al、FeSを原料とした。磁性粒子の組成及び粒径は表1記載のとおりである。組成については、燃焼赤外吸収法で確認し、表1記載以外の成分は全てFeであった。
この原料粒子100重量部を、熱分解温度が400℃であるアクリルバインダ1.5重量部とともに撹拌混合し、潤滑剤として0.5重量部のステアリン酸Znを添加した。その後、トロイダルの形状に表1記載の成形圧力で成形し、20.6%の酸素濃度である酸化雰囲気中650℃にて1時間熱処理を行い、磁性体を得た。
各磁性体について、燃焼赤外吸収法で組成を測定し、磁性粒子の組成がそのまま反映されていることを確認した。
各磁性体についてSEM観察を行い、酸化膜を介して磁性粒子が互いに結合していることを確認した。
見かけ密度はJIS R1620−1995に準拠する気体置換法によって測定した。
めっき性の評価として、磁性体の端部から0.3mmの長さの電極を銀めっきにより作製し、めっき伸びが生じた結果として0.35mm以上になってしまったものを×であると評価し、さもなくば○であると評価した。
各磁性体の製造に際して、成形後(熱処理前)および熱処理後に透磁率μを測定した。熱処理後のμが熱処理前のμより5%以上大きければ、μ評価が○であるとし、さもなくば×であると評価した。
