Precisely defined granulates ready-to-press for your application
Nanoparticles exhibit unusual improvements in product properties through numerous applications. Until now their application has been limited in many ways by handling. for example, the low bulk volume prevents suitable pressing in the production of ceramics and the manufacture of sufficiently dense moulded forms. Transferring the nano powder as a granulate can solve this problem. We offer granulates made of our nanopowder that are ready-to-press. They are easy for our customers to introduce into the respective process chain.

Progress for the user
Our ceramic granulates can be injected into any production process. The nano effect of ceramic powders allows our customers to obtain especially high degrees of strength and viscosity. You save energy because of the lower sinter temperature for nanopowders and obtain uncommon product performance.
Individual customer-specific properties
In granulate form the nanoparticles are separated from each other but at the same time held together using a suitable bonding agent. This permits manufacture of a moulded form with sufficient density. The bonding agent is dissipated in the course of subsequent sintering.
In order to manufacture the granulate a slurry (nanopowder, fluid, additive) is mixed and then granulated. The composition of the slurry as well as the process parameters for granulation determine the resulting granulate properties. Thus, we can set the granulate hardness, granule size and granule form according to customer specification
Example: nanoscale zirconium dioxide
By transferring our nanoscale zirconium dioxide through a customer-specific granulate, we can obtain precisely the particle properties such as strength, size or form necessary for the pressing and sintering in the respective application. The zirconium oxide granulates are used by our customers to manufacture bioceramics for dental purposes or increasingly as a substitute for metals.
