PURPOSE:To obtain the heat-resisting and yield-strengthened filter of corrugated honeycomb structure by using the material manufactured by sintering a sheet consisting of heat-resisting inorganic fibers, the raw powder for ceramics and nickel oxide (II) powder. CONSTITUTION:The heat-resisting inorganic fibers are suspended in water to form a slurry, which is mixed with the other slurry which is separately prepared with the raw powder of ceramics and nickel oxide (II) having catalytic action and is manufactured into a sheet. By using the sheets, with an adhesive and a plug material, a corrugated honeycomb structure with plugged cells 3-a, 3-b is formed, and is sintered at 1,200-1,350 deg.C to obtain the filter. As for the adhesive, one containing a mixture of the heat-resisting inorganic fibers and the raw powder of ceramics is used. As for the plug material, a high viscous slurry containing the same composition as that of the sheet is used. |
