In the present work, the effect of isolated and non-isolated dust particles on glow discharge of main air plasma charactasrics are investigated experimentally. Our results illustraited that the present of dust particle in the air plasma did not effect on Paschen minimum. This fact means that, the present of both types of dust particles did not effect on the plasma properties in high and low pressure regions (i.e. reight and left regions of Paschen minimum) . As well as, the discharge current is increases when the both dust types are immersed in a plasma column with rate rapidly in the copper oxide dust greater than copper dust particles.
