Carbonyl Iron Powder Description
Carbonyl Iron Powder is an iron powder produced by the decomposition of iron pentacarbonyl in the presence of air and other gases. It is a fine, grey-black powder with high purity and a specific surface area.
Carbonyl Iron Powder has high purity and a controlled particle size distribution, which makes it suitable for various industrial applications. It exhibits magnetic and electrical properties that are beneficial for the production of magnetic materials, electromagnetic interference (EMI) shields and electrical conductors.
Due to its high purity, Carbonyl Iron Powder is frequently used as an iron supplement in the pharmaceutical industry. It is incorporated into formulations such as tablets, capsules and liquids, given that it has good solubility and bioavailability.
Additionally, Carbonyl Iron Powder is utilised as a catalyst in chemical reactions, in the manufacture of diamond tools and grinding wheels, and as an additive in lubricants to enhance wear resistance.

Carbonyl Iron Powder FAQs
Q1: What is Carbonyl Iron Powder (CIP)?
CIP is a highly purified form of iron produced by the carbonyl process and is commonly used as an iron supplement.
Q2: What are the main applications of CIP in food-grade quality?
It is used as a nutritional supplement to address iron deficiency anaemia and is also applied as a food additive.
Q3: Is CIP safe for consumption?
Yes, food-grade CIP is safe for human consumption and is employed in both foods and pharmaceuticals.
Q4: How does CIP help with iron deficiency?
It provides a bioavailable form of iron that may be readily absorbed, thereby contributing to an increase in haemoglobin levels.
