Popis:	The thermal transformation of anhydrous alumina obtained by the decomposition of the lactate, citrate and tartrate of aluminium has been examined by thermal analysis(TGA and DTA), infrared spectrophotometry and X-ray diffraction study. It is found that under an atmosphere of air the thermal decomposition of aluminium hydroxycarboxylates to anhydrous amorphous alumina, which transforms to α-alumina via γ-, δ- and θ-aluminas, proceeds as follows for Al[CH3CH(OH)COO]3, the decomposition of skeleton and the combustion of its decomposition products; for Al[CH2C(OH)CH2(COO)3] and Al2{[CH(OH)COO]2}3, dehydroxylation, decomposition of skeleton and the combustion of its decomposition products.
