【摘要】 比较了两种不同铝胶的性质及添加助剂对铝胶性质的影响，并研究了铝胶的粘度及焙烧后的比表面积．结果表明：两种铝胶的粘度随密度增加而增加；焙烧后具有一定的比表面积，添加胺类分子能增加铝胶焙烧后的比表面积．更多还原

【Abstract】 The characteristics of two different Al-sols and the effect of additives on the characteristics were compared. The viscosity and specific BET surface area of calcined Al-sols were tested. The results show that the viscosity of two Al-sols increases with the increase of specific gravity; The Al-sot crystalline form after calcination exists in the form of r-A1203 Adding the molecules of amine can increase the specific area of calcined Al-Sot and will not influence the formation of r-A1203.更多还原
