<P>PROBLEM TO BE SOLVED: To prevent a ceramic honeycomb structure from being cracked in a firing process and also to prevent the deposition of powder. <P>SOLUTION: A setter is placed on a shelf board, a cell of the setter is buried in heat resistant inorganic powder and a thin powder layer is formed on the upper surface of the setter. A green base ceramic honeycomb structure is placed and fired on the setter through the powder layer, As a result, the crack in the opening end surface of the ceramic honeycomb structure is prevent and further the sintering of the powder is prevented. The average particle diameter of the powder is less than the thickness of the cell wall and is ≤1/2 of the average pore diameter of the cell wall. <P>COPYRIGHT: (C)2009,JPO&INPIT |
