Study on synthesizing high-concentration ozone gas by strong ionic discharge

Alpha-alumina porcelain was used as a dielectric medium to generate ozone. Some influencing parameters, such as applied voltage of electric field, frequency, dielectric medium thickness, and energy consumption, etc., on the concentration of ozone generated were confirmed, and the optimal test for the experimental unit was carried out. The results indicated that strong ionic discharge was gained with the reduced field (E/n) of 300 Td. The ozone generator of miniature and modulus was developed with the ozone concentration of 114 g/m3 and the producing efficiency of 256 g/kWh for the ozone device.
