Discharge and ozone generation characteristics of a ferroelectric-ball/mica-sheet barrier

The discharge and ozone generation characteristics of a ferroelectric-ball (FEB) and mica-sheet double barrier were investigated to study the fundamentals of barrier discharges and to establish better conditions for the efficient control of pollutant gases. Five kinds of FEB's, the dielectric constants of which are 33, 150, 660, 1500, and 10000, were investigated in atmosphere with various pulse frequencies ranging between 0.2-4.0 kHz. It was found that the double barrier has better discharge characteristics for ozone generation than an FEB single barrier. In addition, ozone generation is greatly influenced by both the dielectric constant of the FEB barrier and the applied pulse frequency. As a result, there were optimum conditions for the dielectric constant and the applied pulse frequency to generate ozone effectively which, for the given experimental conditions, were about r=660 and the frequencies higher than 4 kHz.
