<造粒複合体粒子の製造>
ヘンシェルミキサー内に平均粒径0.24μmの球状マグネタイト粒子1Kgを仕込み、十分に良く攪拌して、次に、エポキシ基を有するシラン系カップリング剤(信越化学工業製「KBM−403」(商品名))5.0gを添加混合して表面処理した。
得られた造粒複合体粒子を内容量15Lの静置式熱処理炉内に入れ、窒素ガスを3L/分の流量で流しながら、600℃で2時間熱処理した。室温まで冷却して、マグネタイトと炭素からなる複合体粒子を得た。
得られた複合体粒子200gを1Lフラスコに入れ、5N−塩酸を600ml加え、攪拌しながら70℃で約3時間酸処理した。室温まで冷却し、固液分離した後、乾燥して多孔性複合体粒子を得た。
