Abstract
Official abstract text for this publication.
An ozone generation apparatus includes a cylindrical shaped first electrode, a cylindrical shaped second electrode disposed coaxially with the first electrode and disposed in the first electrode, a dielectric disposed between the first electrode and the second electrode. Dry air is supplied between the first electrode and the second electrode as raw material gas. A discharge gap length d formed by the first electrode, the second electrode, and the dielectric is set to be in a range of 0.3 to 0.5 mm. A pd product, which is a product of the discharge gap length d and a gas pressure p of the raw material gas, is in a range of 6 to 16 kPa·cm. And the discharge gap length d and the gas pressure p of the raw material gas are set to satisfy following expression. ( pd −250 d −3.16 ) 2 +150 d ≦12.5.
