Nucleation and Growth of Cobalt and Iron Silicide Nanoparticles in RF Induction Thermal Plasma Reactor

The nucleation and growth mechanism of cobalt (Co) and iron (Fe) silicide nanoparticles from metals themselves in an induction thermal plasma reactor at atmospheric pressure has been described. The parameters which affected the metal composition of silicides, particle size distributions and morphology of silicide nanoparticles have also been discussed. It was found that synthesized Co silicides have large particle size distribution than that of Fe silicides, and Co silicides formation strongly depended on quenching position but Fe silicides did not
