15. Carbonyl iron powder can be obtained by the thermal
decomposition of Fe(CO)5.
Fe(CO)5 is obtained by reacting Fe and CO gas at high
temperature and high pressure: Fe(CO)5 → Fe + 5CO

Equiv-Carbonyl iron powder is a highly pure form of
iron powder with the purity of 99.5% for. It is
manufactured using the electrolysis process and this
is the reason why it is highly pure with superior
electromagnetic properties. In the process of
purification, impurities like carbon, oxygen, and
nitrogen are drawn out.

18. Spherical Shape Iron Powder Manufacturing
Process With Vacuum Melting Gas Atomization
Working principle:
1. Metal or alloy materials are melted under inert
gas protection or vacuum condition, and the
molten metal is poured through insulation tundish
system into a gas nozzle where the melt stream is
disintegrated into droplets by high pressure inert
gas stream.
2. The small droplets will be solidified into tiny
spherical powders in flight in the atomization
tower.
3. Vacuum melting inert gas atomization powder
manufacturing equipment is designed for
producing metallic spherical powder by atomizing
under certain conditions.
