Title:
多孔体の製造方法、多孔体及びハニカム構造体
Document Type and Number:
Japanese Patent JP5095215
Kind Code:
B2
Abstract:
In producing a honeycomb filter 10, silicon carbide serving as an aggregate and alumina serving as a sintering aid that accelerates sintering of silicon carbide are mixed such that the amount of alumina is 1.0% by weight or less relative to the total amount of silicon carbide and alumina to form a puddle, the puddle is molded at a pressure of 20 MPa or less, and firing is performed at a firing temperature that is lower than the temperature at which sintering is performed without mixing a sintering aid. In the honeycomb filter 10 produced by this production method, the bending strength at 900
C is 55% or more (in particular, 80% or more) relative to the bending strength at room temperature.
