从含锑烟尘中制备纳米立方晶型Sb_2O_3

以含锑烟尘为原料,经脱杂处理后,采用真空蒸发法制备了立方晶型纳米三氧化二锑,并用XRD衍射和SEM扫描电镜对产物三氧化二锑进行表征。结果表明,制备的三氧化二锑为立方晶型,颗粒粒径为35~100 nm。实验考察了脱杂时间对脱杂效果的影响;考察了蒸发温度、压强、蒸发时间3个因素对三氧化二锑颗粒粒度的影响。

Preparation of nanometer cubic crystal antimony trioxide from dust containing antimony

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.
