| Abstract: | The porous alumina washcoat coating on cordierite honeycomb was prepared by microwave heating method.The effects of different preparation parameters on the loading,crystal composition,and pore structure of the alumina coating were studied,and then the alumina washcoat prepared was characterized by BET and SEM tests.The results indicate that the alumina washcoat prepared by microwave heating method is stable and uniform with higher Al2O3 weight ratio,larger surface area and pore volume. |
