LPGと酸素ガスによって形成された高温火炎中に、アルミナ粉末を供給し、球状化処理を行った。LPG量の調整によって、平均粒径と平均球形度と表面OH基数の異なる球状アルミナ粉末原料A〜Kを製造し、それをシランカップリング剤A〜Dにより表面処理を行った。表面処理は、ボール径20mm、ボール充填率50体積%の10リットル容器内に、球状アルミナ粉末原料1kgとシランカップリング剤の表1に示される添加量(外割%)とを投入し、常温、常圧の条件下、1回/秒の速度で1時間運転後、120℃にて1時間乾燥させて行った。シランカップリング剤は、一般式、X3−Si−CnH2n−O−Y(但し、官能基X、Yと、n数は表2に記載。)、である。
表3の割合で調合された樹脂分45質量部と、球状アルミナ粉末A〜K又は溶融球状シリカ粉末Lの55質量部とを混合し、E型粘度計型(東京計器社製「EHD粘度計」)により、温度40℃、5rpmの回転数による粘度を測定した。
表4の割合で調合された樹脂分40質量部と、球状アルミナ粉末A〜K又は溶融球状シリカ粉末Lの60質量部とを混合し、JIS K 6911に準じて、175℃、6.9MPa、成形時間2分の条件で10×4×100mmの抗折棒を成形し、室温強度、弾性率を測定した。
アルミニウム配線を有する16ピンモニターICをトランスファー成形し、硬化後260℃のハンダ浴に10秒間浸漬した後、120℃、2気圧の水蒸気中で20V印加してアルミニウム配線のオープン不良率(断線率)とリーク不良率(アルミニウム線間の洩れ電流値が10nA以上になった率)との和が50%以上になるまでの時間を求めた。試料個数は20個である。
実施例6、7では、球状アルミナ粉末原料Bに球状溶融シリカ粉末Lを混合した。実施例8では、球状アルミナ粉末原料B、Hを用い、極大ピークを2つ有し、その1つが3μm以下である球状アルミナ粉末原料を調整した。実施例9では、実施例8において、更に球状溶融シリカ粉末Lの混合された球状アルミナ混合粉末原料を調整した。これらの原料を実施例1の球状アルミナ粉末原料のかわりに用いたこと以外は、実施例1と同様にして試験した。それらの結果を表7に示す。
