Abstract

An ozonizer is disclosed, having a first electrode and a second electrode between which a discharge gap is formed, a dielectric being arranged between the first electrode and the second electrode. The dielectric comprises a support element made of glass or glass ceramic, onto which a thin dielectric film on the order of up to 100 .mu.m is applied. The use of glass or glass ceramic as the dielectric, in conjunction with an additional thin ceramic dielectric film, allows a considerable improvement in the ozone concentration in the carrier gas, simultaneously with a good ozone yield.
