Abstract:
Ceramic rods have been sintered in cold wall single mode microwave cavities under a variety of conditions, including microwave heating and plasma heating. High sintering rates, high density and fine grain sizes were achieved for Beta-alumina and A12O3-TiC composites under favorable conditions. Thermal run-away often was observed in alumina during microwave heating if the heating rate was more than a few degrees per second. On the other hand, microwave plasma sintering of alumina was accomplished at very high heating rates 100 Ks.
