The porous γ-AlOOH powders were obtained by the hydrolysis of aluminum isopropoxide inthe alkaline (C6～9)solutions. The disperse α-Al2O3 powders, with the mean diameter of 70 nmand apparent density of 0.14 g/cm3,were obtained by the calcination of said γ-AlOOH powdersat suitable temperature.The thermal behavior and changes in powder morphology of AlOOH dur-ing the calcination process were also discussed.
