CERAMIC HONEYCOMB FILTER AND METHOD FOR MANUFACTURING SAME
코디어라이트(cordierite)로 이루어지는 다공질의 격벽에 의해 형성된 다수의 유로(流路)를 가지는 세라믹 허니컴 구조체와, 상기 세라믹 허니컴 구조체의 소정의 유로에 형성된 봉지부(plug)를 가지고, 상기 봉지부는, 세라믹 입자 및 상기 세라믹 입자의 사이에 존재하는 비정질(非晶質) 산화물 매트릭스로 이루어지고, 상기 봉지부의 단면에 있어서, 봉지부의 축 방향 길이 중, 한쪽 단부로부터 1/3×t의 범위에서의 비정질 산화물 매트릭스의 면적율 A1과 다른 쪽 단부로부터 1/3×t의 범위에서의 비정질 산화물 매트릭스의 면적율 A2가, 식: 1/2≤A1/A2≤2를 만족시키는(단, t는 봉지부의 폭) 것을 특징으로 하는 세라믹 허니컴 필터.
A method for producing a ceramic honeycomb filter comprising a ceramic honeycomb structure having pluralities of flow paths partitioned by porous cell walls made of a material comprising cordierite as a main crystal, and plugs formed in predetermined flow paths of said ceramic honeycomb structure, comprises charging a plugging material comprising at least 100 parts by mass of ceramic particles, 5 to 20 parts by mass on a solid basis of colloidal oxide and 1.5 to 4 parts by mass of a binder into the predetermined flow paths of said ceramic honeycomb structure, and drying said plugging material by microwave heating or high-frequency dielectric heating to form said plugs; said ceramic particles having a particle size distribution comprising at least a first peak and a second peak lower than said first peak, said first peak being in a particle size range of 100 to 200 µm, and said second peak being in a particle size range of 10 to 30 µm.
