Synthesis and Characterization of Aluminium Nanoparticles by Electric Arc Technique

Abstract

In this work, a process which generates a plasma phase on metal was developed by the electric arc method. The arc process was carried out at constant current and electrode gap which was adjusted by an automatic control system. Particles formed after arc-plasma were stored in cooling liquid with the effect of gravitational force. Electric arc discharge was a successful technique to synthesize aluminium nanopowders with median particle sizes' range from 51 to 139 nm using different processing parameters such as currents and diverse media [distilled water (DW), ethylene glycol (EG)]. The synthesized particles were characterized by several techniques like scanning electron microscopy (SEM), XRD, BET and Nano ZS in order to develop deep understanding for correlation between material properties and fabrication parameters.
