Study Of Oxidation Behavior Of Zn And Fe Nanoparticles

摘要

Zn and Fe nanoparticles prepared by the arc was used in the present study.It were oxidized by laying in the air The microsturctures,oxygen content and oxygen atoms position in nanoparticles were investigated.The results showed that the effective size of oxidized nanoparticles was about50-100nm,particles with a complete form,Particle radius and dislocation density of Oxidated Zn nanoparticles have not change much compare with Zn nanoparticles.Only the strain increase.Fe nanoparticles oxidation lead particles strain rising sharply,and the dislocation densities have decreased slightly,the oxidation occurs in the surface of Fe nano-particles,and generated Fe2O3.After Zn nanoparticles oxidized,Formed ZnO Particles on the surface.
