摘要：
High-power 28 GHz millimeter-wave radiation was applied to the fabrication of bulk AlN, Si3N4 and Al2O3. Millimeter-wave radiation enables the rapid sintering of these ceramics at a temperature from 50°C to 300°C lower than that of the conventional method. The rapid sintering is attributed to the enhancement of atomic migration due to the nonthermal effect of the millimeter wave. It is indicated that millimeter wave radiation can be used for the efficient fabrication of bulk ceramics.
