| dc.description.abstract | The developing of nanosystems has been intensely studied because of their efficiency when applied to pharmaceutical excipients, frequently called as drugs delivery systems. Sol-gel obtained pseudoboehmite, a fine synthetic ceramic precursor of alumina, shows itself as very promising due to its adsorption/desorption properties with pharmaceutical molecules. The use of factorial planning of two levels is very effective in preliminary studies about the possible influence of specific factors in the reagent conversion to a product. A method of pseudoboehmite obtainment was adopted, that has been already reported. The factorial planning 23 used for the pseudoboehmite synthesis involved three variables of synthesis: temperature (A), the aluminum nitrate (Al(NO3)3· 9H2O) concentration (B) and the ageing time (C). The X-ray diffraction data shows that the aging time has influence in the crystalinity of the synthesis product. © (2012) Trans Tech Publications, Switzerland. | |
