Abstract:
The gas combustion flame technology refers to the formation of nanomaterials from gases in flames. Flame synthesis which has many advantages, such as continuous, scalable, without posttreatment, low cost and large quantities, has become an established way to produce nanomaterials with desired characteristics on an industrial scale. The flame aerosol synthesis for the nanoparticles involves the following processes such as rapid hightemperature vapor reaction, the nucleation, growth, agglomeration, and so on. Meanwhile these processes correlate and interact, which making complex for the formation of nanomaterials. Therefore, the study of the preparation of nanoparticles and the corresponding growth mechanism in this complex flame environment has become the research emphasis in recent years. In this paper, we mainly introduced flame reactor, material preparation, structure control, application filed and commercial process base on flame aerosol process, and to explore its possible development in the future.
