Abstract
Temperature and time resolved X-ray diffraction was applied to studies of the high temperature oxidation of iron in air in isothermal measurements between 700 and 920 °C. With the measured series of diffraction patterns the formation of the oxide layers can be followed in situ. The observed diffraction peaks allow the identification of the oxides. The difference method together with microscopic determination of the end thickness of the oxide layer yields the kinetic parameters for the whole oxide layer as well as for the single oxides.
