Ferrochrome - an overview | ScienceDirect Topics

The oxide can be reduced by aluminium (aluminothermic process) or silicon: C r 2 O 3 + 2 A l → 2 C r + A l 2 O 3 2 C r 2 O 3 + 3 S i → 4 C r + 3 S i O 2 The main use of the chromium metal so produced is in the production of non-ferrous alloys, the use of pure chromium being limited because of its low ductility at ordinary temperatures.
