Carbonyl iron is a highly pure (97.5% for grade S, 99.5+% for grade R) iron, prepared by chemical decomposition of purified iron pentacarbonyl. It usually has the appearance of grey powder, composed of spherical microparticles. Most of the impurities are carbon, oxygen, and nitrogen.
Additional recommended knowledge
In electronics, carbonyl iron is used to manufacture magnetic cores for high-frequency coils, and in production of some ferrites. Spherical particles manufactured of carbonyl iron are used as a component of the radar absorbing materials used in military for eg. stealth vehicles. Other uses are in powder metallurgy, metal injection molded parts, and in various specialty products.
Powdered cores made of carbonyl iron have high stability of parameters across a wide range of temperatures and magnetic flux levels, with excellent Q factors between 50 kHz and 200 MHz. A popular application is in broadband inductors, especially in high-power applications.
Particles of carbonyl iron (20-40%) suspended in a carrier fluid (60-80%) are used as a magnetorheological fluid.
