Iron powder as secondary raw material

We develop processes for the production of high-quality iron powders from iron-bearing secondary raw materials. By reducing suitable feedstocks in hydrogen, spherical iron powders can be produced and prepared for subsequent powder metallurgical processing.

Through careful control of the process and heat treatment, the properties of the powders can be tailored to the specific application. These include, in particular:

• Particle size and particle size distribution
• Particle morphology and surface characteristics
• Porous or dense particle structure
• Sintering activity

This enables application-specific powders to be produced from iron-containing residues and waste materials for reuse as engineering materials.
