Controlled Synthesis of Nanosized (5 to 50 nm) Particles and their Agglomerates by Aerosol Processes

摘要CTS-9527999 将研究温度、时间历史和材料性质对纳米颗粒（5至50 mn）形成的影响。 在自由射流火焰、熔炉或激光烧蚀气溶胶发生器中，将研究某些金属氧化物和金属的粒度和附聚过程。 分析了微量气体对一次粒径的影响。 与理论相比较的聚结速率的测量将提供纳米相固态扩散系数。 该工作对超细粒子的合成、焚烧炉产生的残渣颗粒的控制以及等离子体加工过程中污染物的控制具有重要意义。 ***

ABSTRACT CTS-9527999 The effects of temperature, time history and material properties on nanoparticle (5 to 50 mn) formation will be investigated. Studies of particle size and agglomeration processes of certain metal oxides and metals will be investigated either in a free jet flame, furnace or laser ablation aerosol generators. The influence of trace gases on primary particle size will be analyzed. Measurements of coalescence rates compared to theory will provide the nanophase solid state diffusion coefficient. The work has relevance to ultrafine particle synthesis, control of residue particles resulted from incinerators and of contaminants in plasma processing. ***
