Ozone is an environmental benign chemical substance, being able to replace commonly used chlorine compounds in many processes. It is one of the strongest oxidants surpassed only by flourine in its oxidising power. Therefore ozone is used as a germicide and viricide for the treatment of potable and waste water, as well as for bleaching processes and in further chemical oxidation steps. In general large quantities of ozone are generated by dielectric barrier discharges (DBD) [1, 2, 3, 4]. Only these non-equilibrium gas discharges are suited for an effective ozone generation and since ozone is not chemically stable, and therefore would decay during transportation, it is produced in discharge tubes on site where it is needed in tailored capacity. But since the drawback of fairly high production costs of ozone -especially for large quantities - has not overcome yet, large amounts of hazardous chlorine compounds are still used. The aim of this research project is the development of a novel powerful ozonizer tube which cuts down the production costs and thus causes ozone to be an economically competitive alternative in comparison to traditionally used chlorine compounds [5, 6, 7, 8], Standard ozonizer tubes consist of a borosilicate glass tube with a thermal sprayed metallic coating applied to the inner surface of the tube, that serves as the HV-electrode. In this arrangement the tube itself serves as a dielectric. The metallic inner tube surface is electrically connected via metal brushes. The borosilicate glass is restricted to a permittivity of ε_r ≈ 4,6.
