CERAMIC HONEYCOMB FILTER AND METHOD FOR MANUFACTURING SAME
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.
