Metal Powder Characterization

Precision is paramount for making improvements in material design. In modern technology, metal powders are used in many different industries and for an extensive range of applications. This results in very diverse requirements due to the varied uses, e.g. additive manufacturing, casting, coating or additive in paints and inks, as well as a large range of industrial applications such as powder metallurgy, metal injection molding and toolmaking. Identifying powder properties is vital in order to know about physical properties. We investigate properties such as flowability, surface area, porosity, and size homogeneity, which affect the production process, as well as the final product quality.

The microscopic properties of metal powders are of central importance in order to guarantee high quality of the raw as well as the final product. Typical powder analysis methods such as powder rheology, particle sizing, BET area and density measurements are, therefore, used for assessing the physical properties of these materials.

One typical application for the use of metal powders is 3D printing in the young field of additive manufacturing. Additive manufacturing processes, also known as layer construction processes, make it possible to create products of any size and complexity. This method is used in many industries including:

  • consumer goods,
  • medical technology,
  • architecture, and
  • aviation industry.
