Abstract

PURPOSE:To highly efficiently catch fine particles and at the same time to prevent the caught fine particles from being blown off, by making activated alumina adhere to and incorporating a foamed-ceramic molded body at the specific rate to the weight of the body. CONSTITUTION:Activated alumina is coated to adhere to the inner surface of a foamed cell of a foamed ceramic body consisting of cordierite and alumina, etc. At this time, the coating amount of alumina is made within a range of 2- 40wt% alumina or preferably within a range of 10-30wt% alumina. Further, as activated alumina, of which crystalline phase consisting of gamma-alumina or eta- alumina is preferable, and average 5-30mum as the particle size is also preferable.
