摘要 |
<p>A process for producing a honeycomb structure includes: a mixing step where forming raw materials including a ceramic raw material are mixed to obtain a forming blended material, a kneading step where the forming blended material is kneaded to obtain kneaded clay, a forming step where the kneaded clay is formed into a honeycomb shape to obtain a honeycomb formed article, and a firing step where the honeycomb formed article is fired to obtain a honeycomb structure. The ceramic raw material is a cordierite forming raw material, and a magnetic powder contained in the kneaded clay is at a ratio of 400 ppm or less with respect to solid content conversion mass of the whole kneaded clay. There is provided a honeycomb structure capable of improving trapping efficiency, in particular, initial trapping efficiency by reducing the number of coarse pores in the partition walls.</p> |
