Abstract
【解決手段】炭化珪素から実質的に構成され、炭化珪素の結晶粒子とその粒界部及び気孔とを有し、且つ炭化珪素の結晶粒子を、二酸化珪素を主成分とする酸化物で結合した構造を有する酸化物結合炭化珪素質材料である。常温及び高温時における曲げ強度が100MPa以上であり、且つ嵩比重が2.65以上である。
【選択図】なし
Description
SiC及びSiO2を焼成後に表1に示す組成になるように調製するとともに、微量成分として、表1に示す添加剤を酸化物換算で1質量%添加し、更に分散材(物質名:ポリカルボン酸アンモニウム)、バインダー(物質名:ポリアクリル酸エマルジョン)及び水を添加したものを50kgボールミルにて、24時間混合し、泥漿をそれぞれ得た。得られた泥漿を、真空中で30分間脱泡処理を施した後、石膏型に泥漿を注泥する鋳込み成形で、成形体をそれぞれ得た。得られた成形体を大気雰囲気下で1400℃焼成することにより、酸化物結合炭化珪素質材料である焼結体(サイズ:400mm×400mm×10mm)を得た。それぞれ得られた焼結体の特性(嵩比重、常温及び1300℃における曲げ強度、1300℃における耐酸化性、耐クリープ性及び耐熱衝撃温度)を測定し、その結果を表1に示す。
(1)焼結体の密度(嵩密度)の測定
『JIS R 2205 耐火れんがの見掛気孔率・吸水率・比重の測定方法』により密度(嵩比重)を測定した。
(2)焼結体の曲げ強度試験
『JIS R 1601 ファインセラミックスの曲げ強さ試験方法』における4点曲げ強さにて測定した。
表1に示すように、実施例1〜8は、微量成分として、原子番号22から29までの遷移金属元素であるTi、V、Cr、Mn、Fe、Co、Ni、Cuが泥漿に添加することにより、得られた焼結体のすべての特性(常温及び1300℃における曲げ強度、1300℃における耐酸化性、耐クリープ性及び耐熱衝撃温度)が良好であった。一方、比較例1〜3では、得られた焼結体の特性が不十分であった。
表2に示す粒子配合を有するSiC、SiO2及びV2O5を、焼成後に表2に示す組成になるように調製し、更に分散材(物質名:ポリカルボン酸アンモニウム)、バインダー(物質名:ポリアクリル酸エマルジョン)及び水を添加したものを50kgボールミルにて、24時間混合し、泥漿をそれぞれ得た。得られた泥漿を、真空中で30分間脱泡処理を施した後、石膏型に泥漿を注泥する鋳込み成形で、成形体をそれぞれ得た。得られた成形体を大気雰囲気下で1400℃焼成することにより、酸化物結合炭化珪素質材料である焼結体(サイズ:400mm×400mm×10mm)を得た。それぞれ得られた焼結体の特性(嵩比重、常温及び1300℃における曲げ強度、1300℃における耐酸化性、耐クリープ性及び耐熱衝撃温度)を測定し、その結果を表2に示す。尚、実施例17は、実施例2と同様である。
表2の結果から、実施例9〜21は、最大粒子径50〜200μmの骨材粒子に、最大粒子径10μm以下の微細粒子を添加したSiCと、焼成後の組成が0.05〜5.0質量%のSiO2及び0.05〜5.0質量%のV2O5になるように調製された泥漿を鋳込み成形した後、焼成することにより、得られた焼結体のすべての特性(常温及び1300℃における曲げ強度、1300℃における耐酸化性、耐クリープ性及び耐熱衝撃温度)が良好であった。一方、比較例4〜28では、得られた焼結体の特性のいずれかが不十分であった。
実施例2で得られた酸化物結合炭化珪素質材料(焼結体)の微構造をSEM(走査型電子顕微鏡)で観察した。その結果を図1に示す。一方、比較例29は、日本ガイシ株式会社からカタロンの商品名で市販されている酸化物結合炭化珪素材料の微構造をSEM(走査型電子顕微鏡)で観察したものである。その結果を図2に示す。
実施例2で得られた酸化物結合炭化珪素質材料(焼結体)の微構造は、図1に示すように、焼成時における骨材である炭化珪素結晶粒子と結合部である二酸化珪素との組織を制御して、緻密に焼結することができた。一方、比較例29は、図2に示すように、焼成時において骨材であるSiC粒子間の結合部を構成する二酸化珪素とSiC微粒部が非常に気孔が多量の存在する状態で、緻密に焼結させることが困難であった。
