| Abstract: | Nanometer antimony trioxide from the complex slag containing Pb and Sb was prepared at low temperature by the vacuum evaporation method. The structure, morphology, particle size, distribution ranges of the particle size and whiteness of Sb2O3 were characterized by XRD, SEM, laser sizer and whiteness meter, respectively. The influence of temperature, pressure and time on the evaporation rate of Sb, the purity and whiteness and average particle size of Sb2O3 was investigated. The results show that Sb2O3 obtained at 893 K and 250 Pa for 2 h has an average particle size of 72 nm, specific surface area of 15.5 m^2/g, whiteness of 90%, and Sb2O3 purity of 98.50% with cubic crystals. |
