Although the development of nanoparticles-based materials has advanced rapidly in recent years, industrial production techniques have not kept pace. At this point there is a substantial need for safe production facillties, enabling the synthesis of large amounts of metallic nanoparticles with controlled and uniform quality (particle size, particle size distribution, chemical composition, etc.). Currently a lot of small scale synthesis routes are available to produce nanopowders but most of these routes run into up-scaling problems and are not able to produce nanoparticles at low prices. Inductively coupled thermal plasma (ICP) processing however is able to produce a large variety of nanosized powders on a continuous base and is therefore a possible industrial candidate. A European project has then been initiated to responding to this need by developing an industrial production line including on-line monftoring systems, assuring at the same time safety for the operating personnel as weil as for the surrounding environment. The nano-structured materials of interest for this project are silicon and silicon-based alloyed nanoparticles, which have a huge potential as anode material in battery applications. The overall objective of this project is to transfer the ICP processing knovvledge and technology investigated at a lab-scale to an industrial scale apparatus for the continuous production of tailored oxygen-free Si-based nanopowders at an industrial production rate.
