GAS PHASE METHOD FOR PRODUCING NANOMETRIC PARTICLES

摘要

The invention concerns a gaseous phase process for the production of nano -scale particles (10) in a reactor (11) for producing nano-scale particles i n the gaseous phase, in which there is interaction between a reaction flow ( 14) and an energy flow (15). This process includes the following steps: - a coupling step of a device for producing gaseous chlorides (12) for this reac tor (11), a step of production of gaseous chlorides from a precursor base in the form of powders (20), and an injection step of such reactional flow (14 ) in the reactor (11).
