摘要
采用感应等离子蒸发冷凝法制备了不同粒径范围的纳米硅粉,并对其物理性能进行研究,重点分析了送料速率与冷却气流对粉末粒度的影响。实验结果表明:在其它工艺参数不变的前提下,纳米硅粉的粒径会随着送料速度的增大而变大,随冷却气流的增大而变小。所制备的纳米硅粉纯净度较高,颗粒形貌呈球形或近球形,且具备较窄的粒度分布。
The nanometer silicon powders in different particle size ranges were prepared with the induction plasma evaporation condensation method, and physical properties of silicon powders were studied. The effect of feeding rate and cooling condition on thepow der particle size was focused on. It indicates that the particle size of nanometer silicon powder would be larger with the higher feed speed, but smaller with the increase of cool ing flow if the other parameters were kept constant. The nanometer silicon powder has higher purity, of which the particle morphology is spherical or nearly spherical, and the particle sizes distribution is narrow
