Method for manufacturing an exhaust gas purifying filter |
摘要 |
<p>The present invention provides an exhaust gas purifying filter that has an increased contact area, between a catalyst supported on the dividing walls of a honeycomb structural body and particulate matter deposited thereon, and can improve the capacity of the catalyst to oxidize the particulate matter, and a method of manufacturing the same. According to the present invention, the exhaust gas purifying filter 1 comprising the honeycomb structural body 10 made of ceramic and the catalyst 2 supported on the surface of the dividing walls 11 of the honeycomb structural body 10 has void ratio, of the dividing wall 11 of the honeycomb structural body 10, in a range from 55 to 80%, and the proportion of surface pores is 20% or higher. <IMAGE></p> |
