Abstract：Using the industrial Sb2O3 powders as raw materials and radio frequency plasma as heat source,Sb₂O₃ nano-particles were prepared by high temperature heating and quenching process.The chemical analysis,specific surface area,particle size distribution,phase and morphology of Sb₂O₃ nano-particles were investigated.The results show that Sb₂O₃ nano-particles prepared by radio frequency plasma method are cubic system,whose average particle size is 30 nm,specific surface area is 90.9 m²/g.
