Abstract
The nano aluminium particles were produced in different ambience by the wire explosion process. The influence of pressure in the exploding wire chamber on the size of the particles was analyzed. Certain physico-chemical diagnostic studies, viz., wide angle X-ray diffraction (WAXD), thermo-gravimetric differential thermal analysis (TG–DTA) studies were carried out to characterize the produced nano aluminium powder. The compositions of the material were characterized through the energy dispersive analysis by X-ray (EDAX) results. The size of the particles was measured using transmission electron microscope (TEM) studies and particle size distribution analyses were carried out by adopting log-normal distribution. The mechanism of formation of nano powder by wire explosion technique was explained in detail.
