The (Nb2O5) niobium pentoxide compound was synthetized by Pechini method. The followed synthesis protocol is promising to obtain Nb2O5 nanoparticles, in orthorhombic phase. This phase was obtained in the samples calcined at 600°C for 2 hours and the submitted at 500°C for 22 hours in gas flow. For the phase determination and crystal structure was performed XRD. The BET method was used to obtain surface area measurements of the obtained oxide. Raman scattering was employed in order to analyze the nanostructures vibrational spectrum and FEG-SEM in order to study the morphology of the obtain oxides.
