Abstract : A method for the production of large single-crystals of Al2O3 comprising the positioning of several small single-crystals of Al2O3 on a substrate in a chamber, the catalytic oxidation of AlCl3 in the presence of water vapor in the chamber and adjacent to the surfaces of the small single-crystals of Al2O3 to form Al2O3 and HCl gas. The produced Al2O3 being deposited on the surfaces of the small single crystals of Al2O3 form a large single-crystal of Al2O3.
