The sequence of formation of compounds in the Al–TiO2–Gd2O3 system is determined using theoretical and experimental evaluations of the aluminothermic reduction of titanium and gadolinium from oxides. The reduction has two stages and proceeds via the stage of titanium monoxide formation followed by the formation of the Al3Ti and GdAl2 intermetallic compounds.
