POROUS MATERIAL, MANUFACTURING METHOD OF POROUS MATERIAL AND HONEYCOMB STRUCTURE
PROBLEM TO BE SOLVED: To provide a porous material hardly being broken when exposed to high temperature under low oxygen atmosphere and having enhanced heat resistance.SOLUTION: There is provided a porous material constituted by aggregates 30 consisting of nonoxide containing silicon and a binder 32 consisting of oxide ceramic by binding the aggregates 30 each other with a state holding a plurality of pores, and having a phase 35 containing oxygen on a surface containing a boundary surface with the binder 32 in the aggregate 30. The porous material has preferably percentage content of oxygen in the aggregate of 2 to 25 mass% of mass of the aggregates.SELECTED DRAWING: Figure 1
【課題】低酸素雰囲気下で高温に晒された場合においても損傷し難く、耐熱性が向上された多孔質材料を提供する。【解決手段】珪素を含む非酸化物からなる骨材３０と、この骨材３０同士を、複数の細孔を保持した状態で結合させた酸化物セラミックからなる結合材３２と、により構成され、骨材３０における結合材３２との境界面を含む表面に、酸素を含む相３５を有する多孔質材料。多孔質材料は、骨材中の酸素の含有割合が、骨材の質量の２〜２５質量％であることが好ましい。【選択図】図１
