This study focuses on the decomposition reaction characteristics of micro-glow corona with solid materials. Micro-glow corona is a very small plasma, which is able to be generated on the tip of a needle electrode at atmospheric pressure. In this study, a hollow electrode with an inner dimeter of 4 mm was used as a counter electrode to generate the micro-glow corona. In addition, a small plate electrode was set behind a solid dielectric sample to keep the micro-glow corona by barrier discharge. AC voltage at 100 Hz was applied to the needle electrode. When the gap distance between the needle electrode and sample was changed from approximately 0.5 mm to 10 mm, the discharge current and discharge onset voltage of the micro-glow corona were investigated. Deterioration was observed in a small area of the sample surface after discharge.
