摘要： Provided is a holding seal material including: alumina fibers, wherein the alumina fibers contain 85 to 98 wt % of an alumina component and 15 to 2 wt % of a silica component, the holding seal material has multiple marks formed by needle punching, and in a heat treatment test, a contact pressure of the holding seal material heated at a test temperature of 950° C. is 65 to 99% of a contact pressure of the holding seal material heated at test temperature of 800° C., wherein the heat treatment test includes: a compressing step of disposing the holding seal material between an upper plate and a lower plate and compressing the holding seal material to a gap bulk density (GBD) of 0.3 g/cm3; a heating step of heating, after the compressing step, the compressed holding seal material to a predetermined test temperature at a temperature-increasing rate of 45° C./min and maintaining the holding. seal material at the test temperature for six hours; a releasing step of cooling, after the heating step, the holding seal material to room temperature and releasing the holding seal material to a gap bulk density (GBD) of 0.27 g/cm3; and a cycling step of repeating, after the releasing step, 1000 times the cycle of re-compression of the holding seal material to a gap bulk density (GBD) of 0.3 g/cm3 and re-release of the holding seal material to a gap bulk density (GBD) of 0.27 g/cm3 so as to calculate the contact pressure (kPa) of the holding seal material by dividing the load at the last re-release in the cycling step by the area of the holding seal material.

摘要： A holding seal material includes inorganic fibers, skin layers provided around the inorganic fibers, inorganic particles included in the skin layers, a first main surface, and a second main surface. Thicknesses of the skin layers satisfy X>Y≧Z. X is a thickness of the skin layer of the inorganic fibers in a vicinity of the first main surface. Y is a thickness of the skin layer of the inorganic fibers in a vicinity of a center of the holding seal material in a thickness direction. Z is a thickness of the skin layer of the inorganic fibers in a vicinity of the second main surface.
