【発明が解決しようとする課題】
本発明は、これらの問題を解決するためになされたもので、セラミック成形体の端面に、封口用ペーストからなる突起や垂れ等を形成させることなく、封口すべきでない貫通孔を封口してしまう等の問題を発生させることなく、適切に封口処理を行うことができるセラミック成形体の封口方法、上記封口方法で封口したセラミック成形体を用いる多孔質セラミック部材の製造方法、及び、上記製造方法で得た多孔質セラミック部材を用いるセラミックフィルタの製造方法を提供することを目的とするものである。 0013
[Problems to be Solved by the Invention]
The present invention has been made to solve these problems, and the through holes that should not be sealed are sealed without forming protrusions or drips made of the sealing paste on the end face of the ceramic molded body. A method for sealing a ceramic molded body that can be appropriately sealed without causing problems such as the above, a method for manufacturing a porous ceramic member using the ceramic molded body sealed by the above-mentioned sealing method, and the above-mentioned manufacturing method. It is an object of the present invention to provide a method for manufacturing a ceramic filter using the obtained porous ceramic member.

また、第二の本発明は、多数の貫通孔が隔壁を隔てて長手方向に並設された柱状のセラミック成形体の上記貫通孔の端部を、セラミック粉末を主成分とする封口用ペーストで封口するセラミック成形体の封口方法であって、封口パターン状に開孔が形成されたマスクを、上記セラミック成形体の端面に当接し、上記封口用ペーストを上記マスクの開孔から上記セラミック成形体の貫通孔に侵入させた後、上記マスクを上記セラミック成形体より上にした状態で、上記セラミック成形体と上記マスクとを引き離すことを特徴とするセラミック成形体の封口方法である。
また、第三の本発明は、第一又は第二の本発明のセラミック成形体の封口方法で封口されたセラミック成形体を焼成処理することを特徴とする多孔質セラミック部材の製造方法である。
また、第四の本発明は、第三の本発明の多孔質セラミック部材の製造方法で製造した多孔質セラミック部材を複数個結束させることを特徴とするセラミックフィルタの製造方法である。 Further, in the second invention, the end portion of the through hole of the columnar ceramic molded body in which a large number of through holes are arranged side by side in the longitudinal direction across the partition wall is used as a sealing paste containing ceramic powder as a main component. A method for sealing a ceramic molded body to be sealed, in which a mask having holes formed in a sealing pattern is brought into contact with the end face of the ceramic molded body, and the sealing paste is applied from the holes in the mask to the ceramic molded body. This is a method for sealing a ceramic molded body, which comprises pulling the ceramic molded body and the mask apart from each other in a state where the mask is placed above the ceramic molded body after being penetrated into the through hole of the above.
The third invention is a method for producing a porous ceramic member, which comprises firing a ceramic molded article sealed by the method for sealing the ceramic molded article of the first or second invention.
The fourth aspect of the present invention is a method for producing a ceramic filter, which comprises binding a plurality of porous ceramic members produced by the method for producing a porous ceramic member of the third invention.
