摘　　要：考察了不同铝胶焙烧后的氧化铝涂层的性质；并对铝胶加入胺类有机化合物进行改性．结果表明：铝胶涂层具有一定的比表面积，负载量随着铝胶密度的增加而增加．在溶胶中加入胺类有机化合物，能较大范围内改变胶的性能、氧化铝的孔结构，极大地增加比表面积．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.
