Generation of aluminum nanoparticles using an atmospheric pressure plasma torch

The effects of plasma gas flow rate, aerosol gas flow rate, and applied power on the shape, size, and size distribution of the aluminum nanoparticles were investigated. The nanometer scale aluminum particles were produced from micron scale aluminum metal particles in an argon plasma. The operating conditions dramatically impacted the average size, the size distribution, and the shape of the nanoparticles. The results show that the distributions tend to show an unusual concentrations of large particles at relatively long residence times and high aluminum feed rates.
