Carbonyl metallurgy is used to manufacture products of iron, nickel, steel, and other metals.
These are metal-ligand complexes where carbon monoxide is bonded to individual atoms of metals .
Both can be formed by the exposure of the powdered metal to carbon monoxide gas at temperatures of around 75 degrees Celsius.
[citation needed] The carbonyl process has been used to produce molds in custom shapes for industry.
Carbonyl metallurgy is useful as a low-temperature metal coating technique that may find many applications in the future.
