Abstract
The firing behavior of beta-Si3N4 powder corroded under hydrothermal c onditions was investigated by transmission electron microscopy (TEM) a nd energy dispersive X-ray spectroscopy (EDX), TEM and EDX analyses su ggested that the hydrothermal treatment enhanced the formation of tran sient growth bands in beta-Si3N4 ceramics containing Y2O3-Nd2O3 additi ve during firing at high temperature. Also, EDX analysis indicated tha t the grain boundary regions around the grown beta-Si3N4 grains contai ned a Y-Nd-Si-O-N phase.
