FIRED CERAMIC HONEYCOMB STRUCTURAL BODY |
摘要 |
<p>The ceramic honeycomb structure according to the present invention includes a cell group having a plurality of cells which are divided each other by porous partition walls and functioning as a fluid channel, and porous outer wall surrounding and holding outermost peripheral cells located at a circumference of the cell group. In the partition walls, a part located at least one opening end of the cells of the cell group constitutes a reinforced partition wall part having higher strength than the other part of the partition walls (normal partition wall part) as well as having a variation of porosity per unit volume within +/-2%. Uniform and excellent erosion resistance is achieved throughout the reinforced partition wall part. <IMAGE></p> |
