Carbonyl Iron Powder

Carbonyl Fe powder is a unique form of iron powder that is produced by thermal decomposition of iron pentacarbonyl, which results in very fine, spherical particles. This unique form of iron powder has several applications across various industries due to its specific properties. Here are some common applications of carbonyl iron powder:

Magnetic Materials:

Carbonyl Fe powder is used in the production of soft magnetic materials, such as inductors and transformers, due to its high magnetic permeability and low coercivity. It helps improve the efficiency of these electronic components.

Powder Metallurgy:

It is widely used as a raw material in powder metallurgy processes to manufacture various products, including sintered automotive parts, gears, and bearings. The fine particle size and purity of carbonyl iron powder make it suitable for these applications.

Metal Injection Molding (MIM):

Carbonyl Fe powder is used as a feedstock material in metal injection molding processes to create complex-shaped components in various industries, including automotive, aerospace, and electronics.

Electromagnetic Interference (EMI) Shielding:

Due to its magnetic properties, carbonyl Fe powder is utilized in EMI shielding applications to protect electronic devices and sensitive equipment from electromagnetic interference.


It is used as a catalyst in chemical reactions, particularly in hydrogenation reactions, due to its high surface area and reactivity. This makes it useful in industries like petrochemicals and pharmaceuticals.


Carbonyl Fe powder is sometimes used as a black pigment in paints, coatings, and inks due to its dark color and magnetic properties.

Microwave Absorbers:

In radar and microwave technology, carbonyl Fe powder is employed as a component in microwave absorbers to attenuate microwave signals, making it useful in stealth technology and radar-absorbing materials.


It can be used in medical applications such as drug delivery systems. Its magnetic properties can be exploited for the controlled release of drugs in targeted areas within the body.

Food Fortification:

In the food industry, carbonyl Fe powder is used for iron fortification in various food products to combat iron deficiency anemia. It is added to foods like cereals and infant formulas.
