Nanopowders synthesis at industrial-scale production using the inductively-coupled plasma technology

The increasing demand for nanopowders (particles size <;100 nm) having very specific properties calls for the development of new technologies that could bring nanopowders synthesis at the industrial scale. The production of rather large volumes of nanopowders involves processing equipments that can provide a complete control of the synthesis conditions in a continuous producing mode with strong reliability, as well as low processing costs. More importantly, such equipments must be designed to ensure the safe recovery and handling of the ultra-fine constituents. Inductively-coupled plasma (ICP) is one of the most promising approach in the production of a wide range of nanopowders with tailored properties, either at laboratory or industrial scales. The ICP technology developed by Tekna Plasma Systems Inc. will be briefly described, while highlighting specific characteristics that make this technology particularly attractive for the synthesis of various types of nanopowder.
