Effect of the Ammonium Aluminium Carbonate Hydroxide Preparation Method on Morphological Properties of Aluminium Oxide

Ammonium aluminium carbonate hydroxide is synthesized by three different ways. The prepared samples and the products of their heat treatment (aluminium oxides) are studied by physicochemical methods. It is shown that the synthetic method used to prepare ammonium aluminium carbonate hydroxide has a significant effect on the structure, porosity, and dispersion of the resulting γ- and α-forms of aluminium oxide.
