Description
本発明の多孔質材料の一実施形態は、骨材と、骨材間に細孔を形成した状態で骨材同士を結合する結合材とを含有し、結合材が、結晶質のコージェライトを含有し、結合材が、希土類元素又はジルコニウム元素を更に含有するものである。そして、本発明の多孔質材料の一実施形態は、上記骨材と上記結合材の合計質量に対する、結合材の質量の比率が12〜45質量%である。
本発明のハニカム構造体の一実施形態は、上述した本発明の多孔質材料の一実施形態により構成され、「一方の端面である第1の端面から他方の端面である第2の端面まで延びる複数のセル」を区画形成する隔壁、を備えたものである。本実施形態のハニカム構造体は、上述した本発明の多孔質材料の一実施形態により構成されるため、耐熱性及び耐熱衝撃性に優れ、焼成温度域が広いものである。上記セルは、流体の流路となるものである。また、ハニカム構造体は、最外周に位置する外周壁を有する構造であることが好ましい。隔壁の厚さは、100〜500μmが好ましく、125〜400μmが更に好ましく、150〜375μmが特に好ましい。セル密度は、15〜77セル/cm2が好ましく、20〜62セル/cm2が更に好ましく、23〜54セル/cm2が特に好ましい。
本発明の多孔質材料の製造方法の一実施形態について、以下に説明する。
本発明のハニカム構造体の一実施形態の製造方法について説明する。
炭化珪素(SiC)粉末と結合材用原料(粉末)とを、75:25の比率(質量比率)で混合して「混合粉末」を作製した。結合材用原料としては、コージェライト化原料として、タルクを7.8質量%、アルミナを10.0質量%、コロイダルシリカを12.9質量%有し、希土類酸化物として酸化セリウム(CeO2)を2.7質量%含有する粉末を用いた。そして、上記「混合粉末」に、バインダとしてヒドロキシプロピルメチルセルロース、造孔材としてデンプン、吸水性樹脂を添加すると共に、水を添加して多孔質材料用原料(成形原料)とした。バインダの含有量は混合粉末を100質量部としたときに、7質量部であった。造孔材の含有量は混合粉末を100質量部としたときに、26質量部であった。水の含有量は混合粉末を100質量部としたときに、35質量部であった。炭化珪素粉末の平均粒子径は18μmであった。また、造孔材の平均粒子径は、デンプン、吸水性樹脂共に、30μmであった。尚、炭化珪素粉末及び造孔材の平均粒子径は、レーザー回折法で測定した値である。
多孔質材料中の各成分の同定は、EPMA(Electron Probe Micro Analyzer)による定性分析及び元素マッピングの結果に基づいて行う。各成分の含有量は、ICP−AES(Inductively Coupled Plasma Atomic Emission Spectrometry:誘導結合プラズマ−発光分光)の方法で定量する。具体的には、珪素(Si)、アルミニウム(Al)、マグネシウム(Mg)、希土類、ジルコニウム(Zr)、炭素(C)、及び酸素(O)の各量を測定する。そして、炭素(C)の量から炭化珪素(SiC)の量を算出する。そして、残りの(炭化珪素(SiC)に含まれない)珪素(Si)を二酸化珪素(SiO2)であるとして、当該二酸化珪素(SiO2)量を算出する。そして、アルミニウム(Al)、マグネシウム(Mg)、ジルコニウム(Zr)及び希土類が、いずれも酸化物であるとして、それぞれの酸化物の量を算出する。そして、上記SiO2、Al2O3、MgO、ZrO2及び希土類酸化物の全体に対する、「結合材」中の各成分(SiO2、Al2O3、MgO、ZrO2及び希土類酸化物)の含有量を算出する。
結晶相の同定(つまり、結合材中に含有されるコージェライトが「結晶質」であることの確認)は、粉末X線回折により行う。つまり、粉末X線回折により、コージェライトが結晶質か、非晶質かを確認する。また、併せて異相(ムライト)の存在の確認を行う。
結合材全体に対する結晶質のコージェライトの質量の比率は、上記X線回折により得られる各結晶相のピーク強度の比と上記誘導結合プラズマ発光分光(ICP−AES)による方法により測定される値とから算出して求める。
気孔率は、水銀圧入法(JIS R 1655準拠)による全細孔容積[cm3/g]と水中アルキメデス法による見掛密度[g/cm3]から算出する。気孔率の算出に際しては、「開気孔率(%)=100×全細孔容積/{(1/見掛密度)+全細孔容積}」の式を用いる。尚、本明細書において、「気孔率」というときは、「開気孔率」を意味する。開気孔率は、「多孔質材料の表面に開口する気孔」についての気孔率のことである。
水銀圧入法(JIS R 1655準拠)により測定する。
ハニカム構造体をセルが貫通する方向を長手方向とした試験片(厚さ0.3mm×横4mm×長さ40mm)に加工し、JIS R 1601に準拠した「曲げ試験」により材料の曲げ強度を算出する。
上記「曲げ強度」の試験により得た「応力−ひずみ曲線」から、その「傾き」を算出し、得られた「傾き」をヤング率とする。
JIS R 1618に準拠して、40〜800℃の平均線熱膨張係数(熱膨張係数)を測定する。
各条件を表1,2に示すものとした以外は実施例1と同様にして多孔質材料(ハニカム構造体)を作製した。実施例1の場合と同様にして、各評価を行った。結果を表1,2に示す。各多孔質材料の気孔率は、造孔材の量を適宜変更することで調節した。
