軟磁性MnZn系電力フェライトは、主成分および副成分を含み、前記主成分は、Fe2O3、MnO、ZnOおよびNiOを含み、主成分の総量において、Fe2O3が53.0〜55.0mol%を占め、ZnOが3.0〜7.0mol%を占め、NiOが0〜1.0mol%を占め、MnOが残部であり、前記副成分は、CoO、SiO2、CaCO3、Nb2O5及びZrO2を含む。
各実施例および比較例に従って、それぞれFe2O3、MnO、ZnOの形態で比率を計算し、Fe2O3、Mn3O4、ZnOという3種類の原料を秤量して配合し、続いて、サンドミルに脱イオン水を加えて混合して40分間粉砕する。10分間繰り返して混合した後、噴霧造粒を行う。
噴霧材料を予熱炉に入れて、850℃で3時間予熱する。
予熱材料に、CaCO3:0.08wt%、SiO2:0.05wt%、Nb2O5:0.02wt%、ZrO2:0.02wt%の補助成分を加える。そのうち、CoOおよびNiOは各実施例および比較例に従って秤量する。続いて、粉末材料をサンドミルに入れて脱イオン水を加えて二次研磨を90分間行う。
二次研磨剤に約0.08wt%のPVA、および0.004wt%の消泡剤を添加し、続いて、噴霧塔中で噴霧造粒を行い、50〜200μmの顆粒にする。異なる実施例および比較例の粒子を、密度が3.00〜3.15g/cm3のH25×15×8mm標準リングブランクに成形させる。
一定の酸素および窒素比で昇温し、1300℃の温度条件で5時間焼結する。焼結時の酸素分圧は5%である。続いて、一定の酸素および窒素比で室温に冷却する。
焼結されたサンプルリングは、日本岩崎会社のSY8218装置で電源Pcvおよび飽和磁束密度Bsの測定を行う。測定条件は、100kHz、200mTの条件でPcvを測定し、50Hz、1194A/mの条件でBsを測定する。
