Abstract

The texture characteristics of aluminum hydroxides peptized by organic acids and then calcined were studied. A decrease in the pore volume and pore diameter for aluminum hydroxide was studied as a function of the amount of a peptizer. The calcination causes basic aluminum salts obtained by peptization to decompose at different temperatures, depending on the strength of a peptizing acid. The observed regularities were explained in terms of the thermal decomposition of organic aluminum salts of varied composition.
