Galvanostatic polarisation experiments have been made on indium electrodes in alkaline solutions. Long time and transient measurements are described. The anodic reaction conforms to passivation due to the progressive growth of a solid film on the electrode surface: under some conditions a precursory solution reaction may be observed. The polarisation behavlour is influenced by semiconductor properties of oxide formed in the indium hydroxide layer. ApplzcatlOn to possIble energy conversion devices is mentioned.
