This presentation is concluding current results of long-term research in development of new specialized ceramic substrates for Dielectric Barrier Discharges (DBDs), in our case coplanar DBDs. We have developed unique method for capturing ignition and quenching voltage [1]. This device is using simple RC high-pass filter, which simply suppress high-voltage signal with frequencies around tens of kHz, whereas low-voltage signal with high-frequency is nearly unaffected. That means that this simple RC high-pass filter can be used for capturing ignition/quenching voltage, thanks to occurrence of high-frequency voltage drops during plasma ignition/quenching (voltage drops are caused due to non-zero impedance of high voltage source). Effectivity of this approach was studied on commonly used ceramic tapes used in industry for Diffuse Coplanar Dielectric Barrier Discharge (DCSBD) [2]. After evaluation of data reproducibility on these types of ceramic tapes, new ceramic tapes with potentially better chemical and physical properties were made [3]. The innovational ceramics tapes were made by tape-casting method incorporating different dopants into aluminum oxide (Al2O3) matrix. In our results, the most advantageous and interesting dopants were magnesium alumina oxide (MgAl2O4) and chromium oxide (Cr2O3). Examples of used ceramic tapes are shown in Figure 1.
