Abstract The thermal degradation processes of the remaining substances in the hydrolysis product of aluminum alkoxide were investigated with evolved gas analysis-mass spectrometry (EGA-MS). Different patterns of the process were obtained from the hydrolysis products with various temperatures which give different products. Concerning boehmite as a 90°C-hydrolysis product, the carbon compounds are eliminated below about 300°C, before dehydration from AlOOH to $Al_{2}O_{3}$ upon heating. Whereas in the case of a boehmite+bayerite mixture as the hydrolysis product at room temperature, dehydration from $Al(OH)_{3}$ to $Al_{2}O_{3}$ takes place almost simultaneously with the elimination of carbon compounds below the temperature of dehydration from AlOOH to $Al_{2}O_{3}.$
