Carbonyl iron powder and other iron powder difference

1. Carbonyl iron powder particle size is relatively fine, generally below 2.5 microns, ordinary iron powder is relatively thick, generally more than 20 microns;

2. Carbonyl iron powder is more pure, less impurities; 

3. The particle morphology of carbonyl iron powder is generally onion-like, and the specific surface area is large. Of course, according to the requirements, carbonyl iron can also be prepared with different shapes of carbonyl iron powder, such as ultrafine spherical fiber sheet, to meet different application needs; 

4. Carbonyl iron powder is expensive
