NOBILTA™ : Feststoffmischen mit hohem Energie-eintrag, Teil 2

The application of nanoscaled oxide ceramics like cerium oxide (abrasives), γ-aluminium oxide (abrasives) and titanium oxide (fillers) has been well known and in common practice for a long time. Nano-structured ceramics have experienced a big boom in recent years and are now the subject of numerous R&D activities. This is due mainly to advances in process engineering (top-down and bottom-up methods), which have yielded processes for the economic generation of oxide nanoparticles in sufficient quantity and quality. The technical, functional, and high performance ceramics based on these nanoparticles have given rise to entirely novel fields of application because of their excellent physical-chemical properties. However, there is still a lack at the moment of suitable process solutions to release the complete potential of nanostructured ceramics. The NOBILTA ™ system by Hosokawa Alpine Aktiengesellschaft based in Augsburg, Germany, which is presented in this article, might prove to provide a possible approach to the solution of this problem. Targeted utilization of the load mechanisms implemented in this system, in conjunction with the material properties depending on the particle size, enables the realization of processes such as mechanically activated, induced reactions, particle fusion by sintering, and particle surface modification.
