Abstract

Ammonium aluminum carbonate hydroxide (AACH) can be obtained from different anions of aluminum sources by a solid-state reaction. Anions play a crucial role on the properties of AACH. It is observed that best-crystallized AACH can be obtained from Al2(SO4)3. Depending on the nature of anion present during synthesis, AACH obtained either from Al2(SO4)3 or AlCl3 has the similar phase transformations calcined at different temperatures, which is different from AACH obtained from Al(NO3)3. The specific surface area (SBET) of alumina prepared by Al2(SO4)3, which is obtained from the calcination of AACH at 500°C, is still in 610.6m2/g.
