The source of impurities in reduced iron powder.

Chemical composition of reduced iron powder.

The chemical properties of the reduced iron powder are the chemical composition of the powder, which mainly includes the total iron content and the content of impurities.
The main component is the total iron content, which has a decisive influence on the performance of the powder.
Other components, including the type and content of impurities, also have an important effect on the performance of iron powder.

The impurities in the reduced iron powder mainly refer to:

1. Combine with iron to form metal or non-metallic components of solid solution or compound: fe-c, fe-s, fe-n, etc.;
2. The inclusion in the process of raw materials and powder production is mainly non-metallic impurities such as si, Al oxide, silicate, etc.
3. Porous reducing iron powder, easy to absorb water in air, oxygen, N, etc.
4. Impurities brought into the flour milling process: mainly C, N, H, etc.
