本発明に係るフェライト粒子粉末をかさ密度が0.5g/cm3以上0.6g/cm3未満であって圧縮度が65%以上に制御することによって、本発明に係るフェライト粒子粉末および/またはボンド磁石用樹脂組成物を用いて作製した成型体の引張伸びが優れることについては未だ明らかではないが、本発明者は次のように推定している。
圧縮度=(タップ密度−かさ密度)/タップ密度×100 (%)
<フェライト粒子粉末の製造>
粉末状のα−Fe2O3とSrCO3とをモル比で2Fe:Sr=5.90:1となるように秤量して、湿式アトライターで30分混合した後、濾過、乾燥した。得られた原料混合粉末にSrCl2及びNa2B4O7の水溶液をそれぞれ添加してよく混合した後、造粒した。このとき、SrCl2及びNa2B4O7の添加量は、上記原料混合粉末に対してそれぞれ2.0重量%、0.2重量%とした。得られた造粒物を大気中1120℃で2時間焼成した。得られた焼成物を粗粉砕した後に、湿式アトライターで30分粉砕し、水洗、濾過、乾燥した。その後、イソプロピルアルコール及びトリエタノールアミンの混合溶液を添加して、更に振動ミルで30分間粉砕した。このとき、イソプロピルアルコール及びトリエタノールアミンを、上記湿式粉砕乾燥品に対してそれぞれ0.2重量%、0.1重量%となる量の混合溶液を添加して、次いで、得られた粉砕物を大気中950℃で1.5時間熱処理した。その後、サンドミルで加重30kg/cmで30分間圧縮・摩砕処理を行い、更にピンミルで解砕処理した。製造条件を表1に、得られたボンド磁石用フェライト粒子粉末の特性を表2に示す。
