β¦ Synopsis
The kinetics of anodic growth of film on tantalum in molten LiNOI, + KNOIl + NaNOI have been studied by employing various cd ratios. accounts satisfactorily for our data. Dewald's double-barrier theory of oxide growth The results are in disagreement with the single-barrier control theory in which space charge is neglected. The kinetics is independent of the electrolyte used.
