Nanosized copper particles were prepared by flowlevitation method. The analyses based on transmission electron microscope (TEM) have been carried out in order to evaluate the average particle size of particles. The relationship between the average particle size and inert gases speed in different temperature and pressure has been established. Combining these characteristic curves, the manufacturing parameter can be obtained. The results shows that the particle size of nanosized copper gradually decreases by reduce the temperature of metal fused drop or increase gases speed. Moreover, to increase the inert gases pressure will deerease the average particle size at 1 200℃.
