Production and application of carbonyl iron powder

Powder metallurgy iron powder is mainly reduced iron powder, atomized iron powder, electrolytic iron powder, in addition to carbonyl iron powder; So what is carbonyl iron powder, what is the production process?


Carbonyl group is an organic functional group formed by a double bond between carbon and oxygen atoms (-C=O-). Carbonyl iron powder is through carbonyl and iron in high temperature and high pressure reaction, the formation of 5 carbonyl iron oil, after low pressure separation of hard iron powder, and then through hydrogen annealing reduction treatment called soft powder, carbonyl iron powder mainly refers to this soft powder, mainly used in injection molding.
