Abstract—The possibility of synthesizing different crystalline modifications of alumina Al₂O₃ by combustion
reactions of a mixture of aluminum nitrate with glycine has been analyzed. Aggregated powders of -Al₂O₃ that
do not transform into the corundum structure after annealing at a temperature of 1000C have been prepared.
The influence of the synthesis conditions on the specific surface area, bulk density, porosity, and morphology
of alumina particles has been investigated.

Key words: combustion reactions, alumina, glycine–aluminum nitrate mixtures, combustion synthesis, ther-
molysis, crystallites, nanopowders
