Abstract

The oxidation kinetics of zirconium of different purities were studied over the temperature range of 600–1300°C (α- and β-phases). The structure of the oxidized specimens was examined. TGA, XRD, EPMA, SEM, metallographic analysis, and microhardness measurements were carried out. Impurity elements were found to increase the oxidation rate of technical zirconium. The mechanism of the effect of impurity elements on zirconium oxidation was shown to differ for the α- and β-phases. Activation energies were calculated for the parabolic and linear stages of oxidation.
