Abstract
Technology was developed to produce high-purity Al2O3, the raw material for manufacturing leucosapphire, which is widely used in metallurgical processes, by electrochemical oxidation of aluminum. The optimum conditions and parameters for the electrochemical process; chemical, granulometric, and phase compositions; and size and shape of the obtained Al2O3 particles are reported. The high-purity Al2O3 could be used in principle to grow leucosapphire crystals by the Verneuil method, horizontal unidirectional crystallization (HUC), and zone refining.
