Research Abstract

Microwave heating enables direct temperature elevation inside materials. Because of its various advantages over conventional methods, such as rapid and selective heating, as well as its ability to internally heat substances, microwave heating can reduce the time and lower the energy consumption necessary for material processing, although the investigations into physical process in solids at GHz band which enables such properties are limited.
On the other hand, we have observed direct reduction phenomena under microwave irradiation on TiO2 and ZnO ceramics in vacuum, accompanied with emissions of reactive atomic oxygen plasma.
In the present study, we constructed a model and analyzed luminescent phenomena during such plasma emission directly induced by microwave irradiation on ZnO ceramics.
