摘要：

Alpha-alumina crystallization from boehmite obtained from a gel was studied as a function of heating temperature and residence time. X-ray analysis allowed the determination of phases and their crystallite size; fluorescence spectroscopy was also studied as a complementary identification technique. The results reveal the general behaviour of gel-derived Al203 phases and their transformation. The occurrence of an amorphous intermediate state was ruled out. © 1990 Chapman and Hall Ltd.
