    Aluminothermic reaction - Wikipedia

    The aluminothermic reaction is used for the production of several ferroalloys, for example ferroniobium from niobium pentoxide and ferrovanadium from iron, vanadium(V) oxide, and aluminium. The process begins with the reduction of the oxide by the aluminium: 3 V 2 O 5 + 10 Al → 5 Al 2 O 3 + 6 V. Other metals can be produced from their oxides in the same way.Elaboration of Al-Mn Alloys by Aluminothermic Reduction of,,In this paper, the elaboration of Al-Mn alloys by aluminothermic reduction of Mn 2 O 3 powders obtained from anodes of alkaline batteries spent and aluminum beverage cans is studied.
