ABSTRACT
The present work, provides a simple technique for the production of
aluminum nanoparticles based on the explosion of thin aluminum wires in different liquids (distilled water,
ethylene glycol and cyclohexane) by applying 36 Volte DC to two electrodes, one in the form
of thin wire and the other in the form of plate and bring them to in touch
mechanically. The nanoparticles are characterized by x-ray diffraction and
UV-Visible spectroscopy. The x-ray diffraction results reveal that the
nanoparticles continue to routine lattice periodicity at reduced particle
sizes. The UV-Visible absorption spectrum of the liquid solution of the aluminum nanoparticles shows
no characteristic Surface Plasmon Resonance (SPR) peak in the visible region.
The TEM and SEM images show that the aluminum nanoparticles have narrow particle size
distribution ranged from 20 to120 nm with average particle size 80 nm. The aluminum nanoparticles
prepared in water and that prepared in ethylene glycol show, no difference in
their average particle size and distribution, while those prepared in
cyclohexane show smaller sizes. It was observed that the particles have a little
irregular shapes and low agglomerate was observed.
