HONEYCOMB FILTER AND METHOD FOR PRODUCING HONEYCOMB FILTER
PROBLEM TO BE SOLVED: To provide a honeycomb filter which can achieve high filtration efficiency without much higher pressure loss.SOLUTION: A honeycomb filter has a porous honeycomb structure, and contains cordierite as a main component, where a pore size distribution of the porous honeycomb structure satisfies all of the following conditions: (a) D1<7 μm; (b) 10 μm≤D50≤14 μm; and (c) 0.10≤(D90-D10)/D50≤0.78, D1 represents a pore size when 1% of the total pore size volume has a pore size smaller than it, D10 represents a pore size when 10% of the total pore size volume has a pore size smaller than it, D50 represents a pore size when 50% of the total pore size volume has a pore size smaller than it, so-called a median size, and D90 represents a pore size when 90% of the total pore size volume has a pore size smaller than it.SELECTED DRAWING: Figure 1
【課題】圧力損失を余り高くすることなく高ろ過効率を実現可能なハニカムフィルタを提供する。【解決手段】ハニカムフィルタは、多孔質ハニカム構造体を有し、その主成分はコージエライトであり、多孔質ハニカム構造体の細孔径分布が以下の条件を全て満たす。（ａ）Ｄ１＜７μｍ（ｂ）１０μｍ≦Ｄ５０≦１４μｍ（ｃ）０．１０≦（Ｄ９０−Ｄ１０）／Ｄ５０≦０．７８ここで、Ｄ１とは全細孔体積の１％がそれよりも小さな細孔径を有している細孔径であり、Ｄ１０とは全細孔体積の１０％がそれよりも小さな細孔径を有している細孔径であり、Ｄ５０とは全細孔体積の５０％がそれよりも小さな細孔径を有している細孔径、いわゆるメジアン径であり、Ｄ９０とは全細孔体積の９０％がそれよりも小さな細孔径を有している細孔径である。【選択図】図１
