Abstract

The open circuit potential and impedance measurements were used to investigate the corrosion behavior of antimony in 0.1M citric acid solution made to various pH values. The results showed that the antimony surface undergoes spontaneous corrosion in the citrate solutions. Also the properties of the anodic oxide film on antimony were examined by impedance technique. It was found that the antimony surface becomes more passive as the thickness of the anodic oxide film formed on antimony increase. The anodic oxide film on antimony behaves like a non- ideal capacitor. The stability of the anodic oxide film in the aqueous solutions was found to depend on the concentration of the formation medium for the anodic oxide.
