AbstractNanocomposites may exhibit new properties of technical interest. Technical applications require many particles, leading to interaction of the particles thwarting the performance of these materials. To exploit specific nano‐properties, the use of composites preventing the particles from interaction is necessary. This leads to the application of nanocomposites. The most homogeneous composites consist of a core coated with an outer layer of a second ceramic or a polymer. For industrial or at least semi‐industrial production of nanocomposites, a process leading to non‐agglomerated powders in a sufficient quantity is needed. Additionally, coating of the particles with either a second ceramic phase or an organic one is necessary. The Karlsruhe Microwave Plasma Process fulfils these conditions.
