Description
(1)超臨界水又は亜臨界水を用い、温度375℃以上450℃以下、圧力25MPa以上40MPa以下、反応時間5分以上30分以下、窒化ホウ素水スラリーの濃度を1質量%以上10質量%以下で窒化ホウ素粉末を処理する窒化ホウ素粉末の表面酸化方法。
(2)有機修飾剤を添加する前記(1)に記載の窒化ホウ素粉末の表面処理方法。
(3)前記有機修飾剤がチオール類、アミン類又はカルボン酸類である前記(2)に記載の窒化ホウ素粉末の表面処理方法。
ガラスビーカーに図1に示す窒化ホウ素粉末が所定の濃度(図2)となるように水と窒化ホウ素粉末とを混合し窒化ホウ素粉末水スラリーを作製し、超音波ホモジナイザーUS−300T(日本精機製作所製)を用いて、5分間の分散処理を実施し、窒化ホウ素水スラリーを用意した。水は純水を使用した。さらに、5ccの管型のオートクレーブを使用し、図2に示す量の窒化ホウ素水スラリーを充填し、振とう式リアクター加熱攪拌装置(AKICO社製)を用い、加熱、加圧処理を行った。処理温度、処理圧力、処理時間も図2に記載した。処理後は5ccの管型のオートクレーブを解放し、中から処理後の窒化ホウ素水スラリーを取り出した。さらに取り出したスラリーを遠心分離処理した。その後、上澄みの水を除去し、40℃で24時間真空乾燥処理を行い、粉末を得た。
