The properties of calcined alumina-washcoating, such as specific surface areas and structure was investigated and measured by BET and XRD. Effects of amine on modified alumina-washcoating with amine was studied. The results show that amine additives can increase the BET area of alumina-washcoating. The amount of carrier of alumina-washcoating increases with the density of A1-sols. The amine additives can change the structure of alumina-washeoating.
