Formation of Iron Oxides by Surface Oxidation of Iron Plate
Croatica Chemica Acta, 2012 Oxidation of iron plates (α-phase) at high temperatures and in atmospheric conditions was monitored. The composition of oxidation products was analyzed with XRD, Raman and Mössbauer spectros-copies, whereas the morphologies of oxidation products were inspected by FE-SEM.
