dc.description.abstractThe synthesis of pseudoboehmites by sol-gel process is a promising technique for the synthesis of aluminas with high specific surface area and with controlled pore diameter. A pseudoboehmite was obtained by sol-gel process using aluminum nitrate as precursor. The purpose of this work is to study the pseudoboehmite by sol-gel process using different synthesis conditions and the effect of variation the synthesis conditions in the properties of pseudoboehmites and aluminas. A 2n experimental planning was used to study the effect of the 4 synthesis variables: temperature (room temperature of ~25o C and low temperature of -3oC), concentration of ammonium hydroxide, concentration of the PVAL solution and ionizing radiation. The obtained products of the synthesis with different conditions were characterized by various techniques: scanning electron microscopy (SEM), differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and infrared absorption spectroscopy. The samples of the different synthesis were calcined at 1100oC during 4 hours and powder diffraction data of the products were collected in order to compare their crystallinity. The difractograms indicate that these products are well crystallized α-alumina.
