<P>PROBLEM TO BE SOLVED: To provide a corrugated fiberboard laminate which is suitable for producing a silicon carbide honeycomb having a square-shaped cell cross section the same as that of a honeycomb used in the world; and a method for producing a silicon carbide honeycomb structure which has a square-shaped cell cross section the same as that of a honeycomb used in the world and is low in cost and good in thermal shock resistance. <P>SOLUTION: The corrugated fiberboard laminate having a square-shaped cell cross section is prepared by forming paper into a square shape opened in one direction and alternately bonding and laminating the square-shaped paper with flat paper. In the method for producing the silicon carbide honeycomb structure, the corrugated fiberboard laminate is immersed in a slurry containing a thermosetting resin and a silicon powder and then baked in an inert atmosphere to carbonize the thermosetting resin; and the resultant carbonized corrugated fiberboard laminate is subjected to reaction sintering at 1,350°C or higher in vacuum or in an inert atmosphere and impregnated with molten silicon melted at its melting point or higher. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
