dc.description.abstractPseudoboehmite was prepared by sol-gel process using aluminum nitrate as precursor. The 2n full factorial experimental design was used for studying 3 variables: temperature of synthesis, the concentration of ammonium hydroxide (wt%) and the pH adjusts of the aluminum nitrate solution with ammonium carbonate. The samples of the eight syntheses (obtained in different conditions) were characterized by: specific surface area of calcined samples (at 500° C), scanning electron microscopy, thermo gravimetric analysis (TG) and differential scanning calorimetry analysis (DSC). The samples were calcined at 1100° C during 4 hours and the X-rays powder diffraction was obtained. The results show that the DSC and TG curves are similar with the data of the literature. The X-rays powder diffraction of the samples calcined at 1100°C shows that all samples present the α-alumina structure.
