Carbonyl Iron Powder

Carbonyl is a highly pure (97.5% for grade S, 99.5+% for grade R) iron, prepared by chemical decomposition of purified iron pentacarbonyl. Carbonyl Iron Powder is composed of spherical microparticles and most of the impurities are carbon, oxygen, and nitrogen.

BASF invented carbonyl iron powder in 1925 and claims to be the world's leading producer. In 1934, BASF was also involved in the development of the very first magnetic tapes used by the AEG Magnetophon tape recorder: carbonyl iron became the first magnetic recording oxide (although quickly replaced two years later by iron oxide).


Carbonyl Iron Powder or Zero Valent Iron powder in the form of microspheres in the range of 3 to 10 microns. The special technology used to manufacture CIPMS allows production iron microspheres at purity of 99.5% or more.


Carbonyl Iron Powder is an exceptional fine iron powder with outstanding magnetization behavior. Applications include metal injection molding, Inductive electronic components, Microwave Absorption, magnetic ink, magnetic plastic parts.
