Abstract

Formation of Nb2O5 films on aluminum was attempted by sol-gel coating, using NbCl5 as a precursor. The structure and the dielectric properties of anodic oxide films formed on aluminum by sol-gel coating and the subsequent anodizing were examined. Anodic oxide film formed by this process was composed of an inner Al2O3 layer and an outer Nb2O5 layer. The capacitance of the anodic oxide films formed on Nb2O5-coated specimens was at most 34 % higher than that of anodic oxide films on aluminum without coating.
