Abstract:	The amount of Al³⁺ ions migrating into HCl solution from unit surface of Al₂O₃ grows with increasing oxide calcination temperature up to 1123 K, remains unchanged up to 1373 K and then, after the formation of -Al₂O₃, rises sharply. Preliminary rehydration of the surface - and -Al₂O₃ relatively decreases their amount. Al³⁺, Al₂O₃, 1123 1373 , -Al₂O₃ . - -Al₂O₃ , .
