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 Al₂O₃ upon heating. Whereas in the case of a boehmite+bayerite mixture as the hydrolysis product at room temperature, dehydration from Al(OH)₃ to Al₂O₃ takes place almost simultaneously with the elimination of carbon compounds below the temperature of dehydration from AlOOH to Al₂O₃.
