Description
焼成後にコージェライトとなるように、タルク、カオリン、アルミナ、シリカ等を所定の配合割合で調合し、バインダー、界面活性剤、水を加え、所定の配合割合で混合して坏土を得た。コージェライト化原料については、粒度、成分等は最終的には気孔率、熱膨脹率に影響するが、適宜、当業者であれば選定することが可能であり、また、バインダー、界面活性剤についても適宜設定することが可能である。得られた坏土を、焼成後に表1に示すセル構造となるように乾燥、焼成段階での収縮率を考慮して、スリット幅を調整した口金を付けた押し出し成形機を用いて押し出し成形を行い、乾燥、焼成後に直径が100mmで長さが100mmの、セルの形状が略正方形となるハニカム構造体を作製した。
実施例1において、セル構造を表1に示すように変えたこと以外は、実施例1と同様にした。平均排ガス温度の上昇について表1に示す。
