Aluminothermic Chromium Metal Lump is produced by blending Chromium oxide, Sodium Dichromate and Aluminium powder together with other reductants/catalysts, loading the mix into a firing vessel, and igniting it. This produces a chemical reaction, resulting in a reduction of the Chromic oxide to pure Chromium metal, and aluminium slag. Aluminothermic Chromium is widely used in the super-alloy industry, specifically in the production of nickel and cobalt based alloys for aerospace, dental and medical applications, and land-based turbines. Furthermore, it is a key element in heat and corrosion resistant specialty alloys.
