Aluminothermic reactions are exothermic chemical reactions using aluminium as the reducing agent at high temperature. The process is industrially useful for production of alloys of iron. The most prominent example is the thermite reaction between iron oxides and aluminium to produce iron itself: . Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3. This specific reaction is however not relevant to the most ...
A process is provided for the aluminothermic production of low nitrogen containing chromium and chromium alloys, said chromium alloys comprising about 80% chromium, about 20% nickel and less than 0.005% nitrogen, said alloys being especially desirable for use as master alloys in production of super alloys where levels of nitrogen imparted by chromium alloying elements are critical.
