Abstract

The ?-? phase transformation in Si3N4 was studied for seeded samples using an Y2O3-Al2O3 mixture as a sintering aid. The concentration of ?-seeds varied from 0 to 5 wt.%. The results showed that ?-? phase transformation followed the first-order reaction. The calculated activation energy for seeded samples was in the range from 348 to 378 KJ/mol, indicating boundary reaction as the rate limiting step.
