| dc.description | When zirconium is oxidized electrolytically only a portion of the charge passed contributes to the growth of the oxide film produced. It is therefore assumed that the formation current consists of both ionic and electronic components, the former producing film growth, and the latter liberating oxygen. In this paper these components are measured separately.The ionic current is deduced from the observed weight increase. After correction has been made for dissolution of zirconium and for the trapping of volatile compounds within the film a figure of 0.41 μg cm<sup>−2</sup> V<sup>−1</sup> is obtained for the film growth.The electron current is determined from the rate of evolution of oxygen. If the remainder of the total current is ionic, there should result a weight increase of 0.46 μg cm<sup>−2</sup> V<sup>−1</sup>, due to oxidation.The agreement between these two values, which is within experimental error, shows that the basic assumption, namely that both electron and ion currents flow, is correct.From the results the current efficiency, rate of formation, dielectric constant and film thickness are obtained. Under the conditions of the experiment the rate of film growth amounts to 30 Å per volt. |
