This feedstock is then reacted with carbon monoxide under pressure at elevated temperature to form liquid iron pentacarbonyl. Powders suitable for powder metallurgy processes can be manufactured using techniques such as reduction of oxides, atomisation, production from carbonyl derivitives, electrolytic production and mechanical alloying. Process of disintegrating molten metal into small particles by use of compressed air b. The process involves the manufacture of metallic powders and the subsequent welding of these powders into a solid form of the required shape. The use of such large volumes of carbonyl gas in the refineries allows the economic production of a range of nickel powders. Recently, demand for very fine powders for the injection moulding process has given a considerable impetus to the carbonyl process. In the decomposition process, because Fe catalyzes the conversion of CO to CO2, NH3 is usually used as a protective gas to inhibit the reaction. New products can also be made by using the gas stream essentially as a coating medium. 2.
