| With dust containing antimony as raw material, nanometer antimony trioxide was prepared by the vacuum evaporation method after removing the impurity, and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the antimony trioxide are cubic crystal structure, the particle size is 35~100 nm. The influences of evaporation temperature, pressure and holding time on particle size and the evaporation time on the effect of impurity removing were investigated, respectively. |
