## Ahstract -After heating the anodic oxide tilm on tantalum, a constant current or voltage was applied to the specimen in a diluted phosphoric acid solution. and the transient behaviour was examined according to the Frcnkel defect model. Interstitial ions taking part in ionic conduction are captu
The anodic films formed on tantalum in many non-aqueous solutions have been found to consist of two layers. Next to the metal there is a layer of Ta206 with the same characteristics as that of films formed in aqueous electrolytes, while between the TaeOb film and the solution there is a layer which
Changes in the thermal oxidation of zirconium due to the presence of an initial electrolyticallyformed oxide layer are studied. The increase in thickness of the oxide on heating is measured optically and gravimetrically. The effect of the initial layer is the same as if it had been produced thermall
