POROUS BODY, MANUFACTURING METHOD THEREOF, AND FILTER CONSTITUTED OF POROUS BODY
To provide a porous body having enhanced thermal shock resistance.SOLUTION: Disclosed is a porous body including: plural ceramic grains; bonding parts which bond the plural ceramic grains therebetween and including amorphous silicon oxide as a main component; and plural pores provided with outer peripheral edges formed from at least one of the plural ceramic grains and the binding parts. The porous body is characterized by that, in arbitrary plural cross sections of the porous body, a 10% cumulative diameter obtained form a number distribution of an equivalent circle diameter of the plural ceramic grains is in a range of 4-11 μm, a 50% cumulative diameter is in a range of 6-17 μm, and a 90% cumulative diameter is in a range of 11-27 μm.SELECTED DRAWING: Figure 1
【課題】耐熱衝撃性がより高められた多孔質体を提供する。【解決手段】複数のセラミックス粒子と、前記複数のセラミックス粒子間を接合する、主成分として非晶質の酸化珪素を有する結合部と、前記複数のセラミックス粒子及び前記結合部の少なくともいずれか一方で外周縁が形成された複数の気孔と、を有する多孔質体であって、前記多孔質体の任意の複数の断面において、前記複数のセラミックス粒子の円相当径の個数分布から求めた１０％積算径が４～１１μｍの範囲、５０％積算径が６～１７μｍの範囲、９０％積算径が１１～２７μｍの範囲にあることを特徴とする多孔質体。【選択図】図１
