Product Description
The ceramic substrate for DBD ozone generator is commonly made out of 96% alumina. This kind of of technical ceramic material offers the characteristics of superb high electrical insulation, high frenquecy, high-temperature resistance and oxidization resistance. So these features are perfectly match with the need of the ceramic substrate in ozone generators.
We have been producing many standard sizes of ceramic substrate for ozone genetators, as well as support customized service.
