| Abstract | ||
| In the present work, the effect of size of zinc dust particles on AC argon discharge characteristics are investigated experimentally. The plasma characteristics are determined by using optical emission spectroscopy (OES) techniques. The results illustrated that the electron temperature (Te) in the present and absent of Zinc dust particle is reduced with increasing of pressure. The electron temperature decreases with increasing of Zinc dust size. Excitation temperature Tex is reduces with increasing of Ar pressure in present and absent of zinc dust particles. The present of Zinc dust reduce the Tex of Ar in both Zinc dust size. The electron density increasing in the present and absent of both zinc dust size. Furthermore, the introduced of zinc dust in AC discharge increasing of ne. | ||
