respectively based on density functional theory (DFT). The total energy, electronic structure, atomic and bond populations were also calculated. The calculation results of total energy indicate... that the combination force of H-O and Al-O bonds of gibbisite is the smallest and gibbisite may be more easier to be calcined into alumina theoretically. Key words: Al(OH)3; DFT; electronic structure......
