| Abstract: | The solvothermal preparations of α-alumina and boehmite crystallites have been investigated, and the effects of solvothermal
conditions such as reactive medium and temperature on the phase, crystallization morphology and size of the crystallites have
been discussed. The calculation of the stability energies of the growth units of the crystallites has been performed based
on the model of anion coordinate polyhedron's growth unit. The results could explain the formation mechanisms of the crystallites.
