Iron(III) chloride (Ferric Chloride, FeCl3) has been used in the synthesis of Au/Fe nanoparticles. It has been used as oxidative etching agent during the preparation of platinum nanostructures.

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resitance properties.
