Thermogravimetry studies show that the oxidation of aluminum–rare-earth metal (R) melts obeys a parabolic law. The true oxidation rate of the melts is on the order of 10–4–10–3 kg/(m2 s). In the Al–R systems, the minimum oxidation rate corresponds to the compositions of intermetallic compounds. The oxidation rate of a melt is shown to increase with temperature. It is found by IRS (infrared spectroscopy) and XRD (X-ray diffraction) that the melt oxidation products consist of γ-Al2O3, R2O3 (R = La, Ce, Pr, Nd, Y, Sc), CeO2, and rare-earth metal monoaluminates RAlO3 (CeAlO3, LaAlO3, NdAlO3).
