Synthesis of aluminum nanoparticles by electromagnetic levitational gas condensation method

A novel electromagnetic levitational gas condensation (ELGC) system was designed and manufactured for the synthesis of aluminum nanoparticles. Both liquid and membrane filtration systems were used for collecting the nanoparticles. Effects of induction coil design, input power and gas flow rate were investigated. It was found that the wet collection in toluene resulted in a smaller particle size than the dry collection on membrane filter. While using low argon flow rate, coarser particles were produced, high argon flow rate intensified the particle coalescence. The best argon flow rate for the synthesis of aluminum nanoparticles was found about 10-15 lit/min.
