| 摘 要： | 为了研究阳极弧放电等离子体方法在制备镍纳米粉过程中电弧电流、气体压力等工艺参数对纳米粉产率及粒度的影响,寻求制备金属纳米粉的最佳工艺参数.利用X射线衍射(XRD)、透射电子显微镜(TEM)和相应选区电子衍射(ED)、BET吸附等测试手段对样品的形貌、晶体结构、粒度分布、比表面积等性能进行了表征.研究结果表明:本法所制得的镍纳米粉的晶格结构为fcc结构.呈规则的球形链状分布,适当控制工艺参数就能制取粒径范围在20-100nm的金属纳米粉,在其他工艺参数不变条件下,气压升高或电弧电流增大,都会使粒度增大,产率增大. |

| Abstract: | The influence of arc current and gas pressure on the production rate and particle size of metal nanopowders by anodic arc discharged plasma method were studied, and the optimal technology parameters were obtained.The nanoparticles by this process were characterized by X-ray powder diffraction(XRD),transmission electron microscopy(TEM) the corresponding selected area electron diffraction(SAED),BET adsorption to determine the morphology,crystal microstructure,particle size distribution,specific surface area.The experimental results indicated the crystal structure of Ni nanopowders was fcc phase,and distributed uniformly in spherical chain shapes.Properly controlling some experimental apparatus can obtain Ni nanopowders with particle size ranging from 20nm to 100nm.The yield and particle size go up with the raise of arc current or gas pressure when other factors are fixed. |
