Powder characteristics:

Grey ultrafine powder, spherical particles, onion-like structure. Carbonyl iron powder has the characteristics of extremely high purity, good fluidity, dispersibility, high activity, excellent electromagnetic properties, and good press and sinter moldability.

Application areas:

Carbonyl iron powder is an ultra-fine metal powder prepared by the thermal decomposition of pentacarbonyl iron Fe (CO) 5. Due to its small particle size (below 10um), high activity and irregular shape (layered structure of onion head), it has many unique properties Therefore, it is widely used in military, electronics, chemical, pharmaceutical, food, agriculture and other fields.

Packing:

Packed in iron drums, 25 kg / barrel, 50 kg / barrel, palletized. Can also be packed according to customer's special requirements
