Honeycomb filter and method of manufacturing the same |
摘要 |
<p>A honeycomb filter includes partition walls forming a plurality of cells extending in one direction, and plugging sections alternately plugging the cells at the ends of the honeycomb filter, the partition walls being formed of a porous base material having a porosity of 45 to 70%. When the average pore size of the base material measured by mercury porosimetry is (A) µm and the average pore size of the base material measured by a bubble point method is (B) µm, the average pore size differential rate expressed by "{(A-B)/B}*100" is 35% or less, and the maximum pore size of the base material measured by the bubble point method is 150 µm or less.</p> |
