摘要：
Studies were made of the dehydroxylation of several aluminium hydroxide modifications and the kinetics of alpha-Al2O3 formation. The investigated samples differed in both mineral composition and the level of alkali admixtures. It was found that the rate of formation and the quantity of alpha-Al2O3 depend mainly on the purity of the aluminium hydroxides, while the transition forms of alumina depend on the initial type of the aluminium hydroxide.
