WZR - Ceramic Powders
In general, any ceramic raw material (e.g. aluminium oxide, zirconium oxide, silicon carbide and many more) can be processed with Binder Jetting. Decisive factors are the particle size distribution, the particle shape, the density, as well as the specific surface of the powders used. On the one hand, these material properties indicate the flowability and compactability of the powders. On the other hand, very fine powders with a high specific surface area are crucial to ensure sufficient reactivity during the sintering process.
We at WZR have invested a lot of research and development in powder characterization. For example, we determine bulk and tapped densities, particle size distributions, dynamic flow behavior, and sorption behavior in contact with liquids. With the characterization methods, we are able to develop and produce powder mixtures from different raw materials with desired properties very quickly and in a targeted manner without the entire Binder Jetting process in order to be able to make a statement about the quality of the powder mixture.
