POROUS MATERIAL, HONEYCOMB STRUCTURE, AND PRODUCTION METHOD OF POROUS MATERIAL
To improve oxidation resistance and thermal shock resistance of a porous material.SOLUTION: A porous material 1 comprises aggregates 2 having an oxide film 22 on the surface of a particle body 21 and a binder 3 containing cordierite and joining the aggregates 2 in a state where pores 4 are formed. The binder 3 contains a rare earth component (excluding Ce). The porous material 1 can improve oxidation resistance due to the presence of the oxide film 22. Further, the thermal shock resistance can be improved by lowering the thermal expansion coefficients while securing high mechanical strength.SELECTED DRAWING: Figure 1
【課題】多孔質材料の耐酸化性および耐熱衝撃性を向上する。【解決手段】多孔質材料１は、粒子本体２１の表面に酸化膜２２が設けられた骨材２と、コージェライトを含み、細孔４を形成した状態で骨材２間を結合する結合材３とを備える。結合材３は、希土類成分（Ｃｅを除く。）を含む。多孔質材料１では、酸化膜２２により耐酸化性を向上することができる。また、高い機械的強度を確保しつつ熱膨張係数を低くして、耐熱衝撃性を向上することができる。【選択図】図１
