Abstract

In the present work, we investigate the anodization of Nb in a $K_2HPO_4$ containing glycerol electrolyte at elevated temperatures ($180^{circ}C$). Under optimized conditions, uniformly over the entire anodized surface, self-organized porous $Nb_2O_5$ structures can be formed. The growth rate of highly ordered $Nb_2O_5$ is $1.7{mu}m/min$ at beginning stage of anodization and the overall current efficiency is 70 %.
