Attempt is made to find regularities that control process of formation and change of surface area on thermally dehydrating aluminum hydroxide with aim of determining optimum conditions for preparing U-Al2O3 with maximum surface area from different forms of hydroxides. Knowledge of kinetics of change of surface during thermal treatment of U-Al2O3 enables one to use aluminum oxide as catalyst or carrier operating in definite temperature range, and to select particular form of hydroxide and conditions for thermally treating it. Process of forming microporous structure is connected with recrystallizationrocess by formation of oxide from aluminum hydroxide. Surface of U-Al2O3 obtained from bayerite is mainly determined by size of primary cyrstals. Surface area of aluminum oxide obtained from boehmite, which is needle shaped, is determined namely by surface area of initial boehmite, and is little altered up to 800 C. Surface area of aluminum oxide obtained from bayerite is decreased as result of sintering of primary oxide particles in bulk of secondary particles, starting at 500 C.
