一个更精确,但易于使用的模型,并提出澄清纳米粒子的生长与热等离子体处理中的双组分共凝聚。计算进行的钯-硅和钛-硅系统表明,该模型定量估计通过共凝聚以及成核和凝聚产生的硅化物纳米粒子的粒度分布和组成分布。该模型还成功地获得了任何其他模型都无法获得的信息。因此,详细的硅化物纳米粒子的生长机制最终被揭示。因此,本模型是一个“适应性强”和有用的工具,用于分析纳米颗粒的生长过程,包括共凝聚,具有足够的精度。
A more precise but easy-to-use model is developed and proposed to clarify nanoparticle growth with two-component co-condensation in thermal plasma processing. Computations performed for the molybdenum-silicon and titanium-silicon systems demonstrate that the model quantitatively estimates both the particle size distribution and the composition distribution of the silicide nanoparticles produced through co-condensation as well as nucleation and coagulation. The model also successfully obtains information that cannot be acquired by any other models. As a consequence, the detailed growth mechanisms of the silicide nanoparticles are eventually revealed. The present model is thus an “adaptable” and useful tool for analyzing nanoparticle growth processes, including co-condensation, with sufficient accuracy.
