The present paper refers to experimental studies on alumina, silicon nitride and pottery sintering process using the 28GHz mm-wave energy generated by a Gyrotron is described. The results may be summarized as follows: (1) Work material are densified in low temperature and short time by sintering of microwave heating compared with conventional heating; (2) The sintered bodies exhibited high density and fine crystalline structure. (3) Control of heating is suitable for the mechanism of mocrowave sintering. The cause or mechanism of these phenomena has yet to be sufficiently clarified. It largely depends upon future multilateral studies.
