Generation of metal oxide aerosol particles by a pulsed spark discharge technique

A pulsed spark discharge generated copper oxide aerosol particles has been characterized. Experiments were conducted for spark electrode gap distance from 10 to 30 mm and air flow rates from 3 to 15 l/min. The results show that the average diameter of generated particles can be controlled from 0.2-4.0 μm and the density of particle also can be controlled by changing discharge electrode gap distance and gas flow rates.
