aluminothermic reduction of manganese

Manganese thermite based on manganese (II) oxide

Jul 10, 2008· And that's precisely the problem with the aluminothermic reduction of MnO 2 (manganese (IV) oxide, manganese dioxide): in adiabatic (or near-adiabatic) conditions it runs far too hot. The reaction is often described on Internet posts as 'explosive' (although I can assure you that only if the burning mixture is contained - in a bomb like ...

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
