Abstract

The reduction behavior of metal oxides during microwave/conventional heating and the structure of the heated samples were investigated. We used high vacuum device and microwave heating system. Using our devices, we were able to measure the partial pressure of oxygen almost in real time. In this experiment, CuO, Fe3O4 and rutile were used as samples. After the experiment, we measured the structure of the samples by SEM. As a result, we found that there is a possibility that the microwave heating promotes the reductive reaction for CuO and TiO2. And, we ovserved that grain boundary of the heated samples by microwave has desappeared for TiO2. In summary, it is guessed that the microwave heating promotes reduction reaction and changes the structure.
