A new hybrid sintering process has been developed by replacing all but one laser by microwaves in the existing simultaneous multiple laser process (SIMPLE). Microwave energy has been used to preheat the material before laser radiation, and the synergism between microwave and laser energies could effectively heat the material to temperatures of 1700degreesC and beyond in just a few minutes. Using this process, rapid sintering of 3Y-ZrO2 (3Y-TZP) pellets has been achieved in a few minutes. Microstructural investigations reveal that the microwave-laser hybrid sintered pellets of 3Y-ZrO2 have nanograins averaging about 20 mn. The microwave-laser hybrid sintering process can clearly be a new approach for fabrication of nanoceramics and nanocomposites.
