The efficiency of the electric precipitator is low for the particle resistivity smaller than 10^4 ohm・cm or greater than 10<11> ohm・cm. We observe mainly the region of lower resistivity and investigate some characteristics of lower resistivity dust in a corona discharging field. The graphite that is lower resisitivity, and the cement and the by-product of cement which are higher resistivity are used. The experimental equipment is consisted of discharging electrode, plate-electrode and probe-electrode on which the dust is accumulated. Under the variable applied voltage, the corona current is measured for the various spacing electrodes and the thickness of the dust. We considered the characteristics of these corona currents for three dusts, the peculiar dispersed phenomena for the by-product of cement and etc. It is thought that the results of these experiments and consideration are useful data for raising the efficiency of the electric precipitation.
