MANUFACTURING METHOD OF HONEYCOMB FILTER

A manufacturing method of a honeycomb filter includes a kneaded material preparation process, a forming process and a firing process, wherein the cordierite forming raw material contains at least one of porous silica and fused silica, particle diameters (μm) of 10% by volume, 50% by volume and 90% b...

Beschreibung
Zusammenfassung:	A manufacturing method of a honeycomb filter includes a kneaded material preparation process, a forming process and a firing process, wherein the cordierite forming raw material contains at least one of porous silica and fused silica, particle diameters (μm) of 10% by volume, 50% by volume and 90% by volume, from a small diameter side, are denoted by D(a) 10, D(a) 50 and D(a) 90 in a cumulative particle size distribution of the cordierite forming raw material, and a particle diameter (μm) of 50% by volume from a small diameter side is denoted by D(b) 50 in a cumulative particle size distribution of the organic pore former, D(b) 50 is 40 μm or less, and a cordierite forming raw material and an organic pore former satisfy given expressions.
