Anodization of zircaloy-4 in 0.1M ammonium oxalate has been carried out. Kinetics of anodic oxidation of zircaloy-4 has been studied at a constant current density of 8mA.cm-2 and at room temperature. Thickness estimates were made from capacitance data. The plots of formation voltage vs. time, reciprocal capacitance vs. time, reciprocal capacitance vs. formation voltage and thickness vs. formati...

Chamber experiments may over emphasize peroxy radical cross reactions due to lower concentrations of reactants that directly convert OH into HO 2 .
