Nanoparticles of many different types are finding applications in such diverse areas as advanced materials, medicine, biotechnology and microelectronics. The use of thermal plasma technology, especially the use of induction plasma torches is a powerful technique to synthesize a wide array of nanosized metals, carbides and ceramic particles. However, due to a lack of fundamental understanding on the design and behaviour of the reactors used for the synthesis only a fraction of the synthesized material has the desired particle size distribution. It is often as expensive to separate out this desired fraction as it was to synthesize them. In addition the hard or soft agglomeration of the product often makes it difficult or impossible to use. This project will undertake a fundamental study of nanoparticle synthesis in a commercial type of induction plasma reactor using a model system to study both the control of particle size distribution and agglomeration. The results obtained will be of interest to all researchers using this technology. Our industrial partner is the major world producer of induction plasma equipment and is well situated to apply the results of this research to other systems.

许多不同类型的纳米颗粒正在在诸如高级材料，医学，生物技术和微电子学等各个领域中找到应用。使用热等离子体技术，尤其是使用感应等离子火炬是一种强大的技术，可以合成各种纳米化的金属，碳化物和陶瓷颗粒。但是，由于缺乏对用于合成的反应器的设计和行为的基本理解，仅合成材料的一小部分具有所需的粒径分布。将此所需的分数分开与合成它们一样昂贵。此外，产品的硬或软聚集通常会使很难或不可能使用。该项目将使用模型系统对纳米颗粒合成的基础研究进行基础研究，以研究粒度分布和团聚的控制。所有使用此技术的研究人员都将感兴趣的结果。我们的工业合作伙伴是引发等离子体设备的主要世界生产国，并且在其他系统中非常适合将这项研究的结果应用于其他系统。
