Abstract :
Nanoparticles (NPs) are used as smart materials in some industrial areas. The methods that utilize arc plasma are a good choice in terms of raising production rate of NPs. In this paper, alumina NPs are synthesized from alumina bulk by transferred-type dc arc plasma, and a high-speed observation of the alumina vapor in the arc plasma is carried out in order to investigate on the evaporation behavior of the alumina bulk.
