收集高度对激光—感应复合法制备锌微粉颗粒大小的影响

Effect of Collection Height on the Zinc Particle Size of Synthesis by Hybrid Laser and Induction

采用在较大腔体内不同高度处放置收集片而进行原位收集方法 ,研究了收集高度对激光—感应复合法所制备的锌微粉颗粒大小的影响 ,同时运用经典的蒸发冷凝理论 ,计算了金属锌微粉的颗粒大小与收集高度的关系 ,并与实验结果进行了比较。结果表明 :与经典的蒸发冷凝理论所预测的一样 ,随着收集高度的增加 ,颗粒大小有增加的趋势 ,但增加幅度小。

Effect of collection height on the zinic particle size of synthesis by hybrid laser and induction has been investigated by the in-situ collection method in the different special positions of the bigger cavity.In the meantime,the classic evaporation-condensation theory was used to calculate the particle size.The results of experimental and calculated show that the particle size increases slightly with the increase of collection height.
