The through holes of the filter base are clogged with the sealing member in a checker flag form on each end surface so as to clog the through holes differently from the through holes sealed on the opposite end surface. The sealing member is a sheet-shaped fired body with a thickness of 3 mm or less, and a difference in coefficient of thermal expansion at temperatures of 40 to 800° C. between said sealing member and said filter base is 0.5×10−6/° C. or less. This honeycomb filter has high filtration efficiency, and very high thermal shock resistance and has high bonding strength between the sealing member and the filter base and a low pressure loss.

摘要： In a method for effectively producing ceramic manifolds for thermally insulating exhaust channels, an intermediate product is first formed by drain casting which includes a main ceramic pipe having a plurality of branch pipes extending therefrom whose ends are connected together by elongated connection members in the form of thin plates or bars. Thereafter, the intermediate product is fired and the ends of the branch pipes are then cut off together with the connection members. In this manner, even ceramic pipes complicated in shape readily can be produced by preventing strains and deformations which would otherwise occur during firing of the intermediate product.

摘要： Novel processes have been developed by the present invention for producing hollow ceramic articles. Such ceramic articles are produced by using a water-absorbable mold having water non-permeable faces on an inner surface of the mold at locations corresponding to valve holes. The thickness of a ceramic layer deposited on the inner surface of the mold is controlled by measuring an amount of a lowered liquid surface level of the slurry near a slurry-pouring opening of the mold. Open ends of a hollow ceramic article are formed by cutting corresponding closed ends after deposition of the slurry and firing. A uniform thickness of a slurry deposited onto the inner surface of the mold can be attained by rotating the mold around an arbitrary rotary axis at a rotation speed of 1 to 60 rpm. All ceramic material contained in the slurry fed inside the mold may be deposited on the inner surface of the mold while the mold is being rotated or swung.
