Abstract
The solvothermal preparations of alpha-alumina and boehmite crystallit es 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 calcu lation of the stability energies of the growth units of the crystallit es has been performed based on the model of anion coordinate polyhedro n's growth unit. The results could explain the formation mechanisms of the crystallites.
