Abstract
A plate-type ozone generator having a discharge cell including a box-shaped casing formed by using a dielectric of a quartz containing silicon dioxide having a purity of not less than 99.9%, a discharging gap defined by the interior of the casing, and a flow passage for a material gas defined in the discharging gap by a partition made of a quartz. A material gas inlet section and an ozone outlet section are provided on the discharge cell for communicating with the discharging gap. Each section has a quartz tube and a stainless steel tube joined together by a fused joint made of a covar glass and a covar alloy. The ozone generator does not employ a gasket made of an organic compound or the like, and is capable of stably generating high-concentration high-purity ozone for a long period of time without the risk of leakage.
