The graphene oxide is a material that allows for many possibilities of application as modify agent in a ceramic structure. In this work, different samples of pseudoboehmite, starting by aluminum nitrate and ammonium hydroxide precursors, were obtained by sol-gel process with graphene oxide increasing concentration. The product has been characterized by X-ray diffraction (XRD), thermal analysis (TG, DTG and DTA), specific surface area (BET), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). The results analysis indicate bayerite formation and a decrease of important properties as a specific area comparing with pure pseudoboehmite started by the same precursors.
