The sol-gel process is a methodology to produce porous, vitreous or crystalline ceramics particles started by molecular precursors constituting the kind of inorganic polymerization system. The pseudoboehmite already obtained by sol-gel process is a high purity material with high surface area and high porous homogeneity. Previous studies with this material have been used, besides the aluminum nitrate (Al(NO3)3), precursors to ammonium hydroxide (NH4OH) and sodium hydroxide (NaOH). The production started by a new precursor, the potassium hydroxide (KOH), represents an advance in the use of this material, allowing the incorporation of a new species of agents responsible for improvement of pseudoboehmite properties
