CYLINDRICAL POROUS BODY
To provide a cylindrical porous body, which can make both strength and gas permeability compatible.SOLUTION: A cylindrical porous body comprises a cylindrical ceramic having a plurality of dents formed on a surface thereof. When the longest line segment of line segments joining two points on an outer peripheral edge of the dent is defined as a first line segment and the longest line segment which is orthogonal to the first line segment of the line segments joining two points on the outer peripheral edge of the dent is defined as a second line segment, a ratio of a length of the first line segment to a length of the second line segment is equal to 5 or more, in the specific dent in which the length of the first line segment is equal to 50 μm or more, of the plurality of dents, where the second line segment is orthogonal to the first line segment, at a point different from a middle point of the first line segment.SELECTED DRAWING: Figure 5
【課題】 筒状多孔質体において、強度とガス透過性とを両立させる技術を提供する。【解決手段】 筒状多孔質体は、表面に複数の窪みが形成されている筒状のセラミックを備え、窪みの外周縁上の２点を結ぶ線分のうち、最も長い線分を第１線分とし、窪みの外周縁上の２点を結ぶ線分のうち、第１線分に直交する線分であって、最も長い線分を第２線分とすると、複数の前記窪みのうち、第１線分の長さが５０μｍ以上である特定窪みは、第２線分の長さに対する第１線分の長さの比が、５以上であり、第２線分が、第１線分の中点とは異なる点において、第１線分と直交する。【選択図】 図５
