carbonyl iron powder

Carbonyl Iron Powder

  Carbonyl iron powder is produced by the reaction of CO and iron under high temperature and high pressure, generating pentacarbonyl iron, an oily substance with the molecular formula Fe(CO)5, which is then separated under low pressure to obtain the product.

  Carbonyl iron powder is a spherical, gray, ultrafine powder with a micrometer-scale particle size. It has an onion-skin layered structure with extremely high purity, good flowability, dispersibility, high activity, ultrafine particle size, uniform particle dispersion and size distribution, high density, easy sintering and forming with high hardness, and strong holding power. It has excellent electromagnetic performance and good pressing and sintering molding properties.

  Our carbonyl iron powder is produced through the reaction of carbonyl and iron at high temperatures and high pressures, followed by low-pressure separation of the resulting pentacarbonyl iron oil.

The product is divided into two types:

  1. Carbonyl Iron Powder (We call it Hard Powder): Obtained directly from the above-described process.
  2. Reduced Carbonyl Iron Powder (We call it Soft Powder): Obtained after the hard powder undergoes a secondary reduction process.

*The composition and particle size of the product can be adjusted according to specific customer requirements.

  Carbonyl iron powder has a wide range of applications, mainly including the following aspects:

  1. Catalysts: Carbonyl iron powder is an important organometallic catalyst that can catalyze many organic chemical reactions, such as carbonylation of carboxylic acids, carbonyl reduction of ketones, and carbonylation of olefins. In addition, carbonyl iron catalysts can also be used in petrochemical industry reactions such as gas phase cracking, ammonia synthesis, and methanol synthesis.
  2. Material synthesis: Carbonyl iron powder can be used to synthesize various materials, such as nanoparticles, thin films, and electrode materials. Nanoparticles can be used in catalysis, magnetic materials, and biomedical materials; thin films can be applied to optoelectronic devices, sensors, and other fields; electrode materials can be used for lithium-ion batteries, fuel cells, and more.
  3. Medical diagnostics: Carbonyl iron powder can be used as a nuclear medicine imaging agent for diagnosing and treating diseases such as tumors and bone disorders.
  4. Other applications: Carbonyl iron powder can also be used in chemical vapor deposition, metal printing, and as a coating additive in various fields.
