Abstract
THE only published works on the oxidation of plutonium are by Waber1, Poole2 and Sackman3. Waber and Sackman's work was carried out only in air at temperatures < 100° C, whereas Poole's work was at 320°–480° C in air. In order to understand the mechanism of oxidation, we have found it necessary to compare the oxidation-rate of plutonium in air and in argon under both dry and humid conditions at a temperature sufficiently low that changes in oxidation behaviour are readily detected. Results presented here indicate that oxidation is anodically controlled.
