Summary:

Development of the ultra thin wall ceramic catalytic substrate is necessary to meet increasingly strict emissions regulations. The cell walls need to be thinner in order to improve the warm-up characteristics related to the reduction of emissions and to lower the back pressure. However, the thinner the wall thickness, the smaller the mechanical strength of the substrate becomes. For substrates with 2.5mil wall thickness, we densified a conventional material with 35% porosity to less than 30%[1] to improve erosion resistance. Furthermore, for substrates less than 2.5mil wall thickness, a denser material and strengthened end surface is necessary to protect against erosion. In addition to that, we think that a reinforced periphery is necessary for isostatic strength. In this paper, we evaluated the effect of a densified material, strengthened end surface, and a reinforced periphery
