%X The effect of holding time on intergranular phase and mechanical property of GPS silicon nitride ceramics was studied. Results show that the contents of intergranular oxygen and total grain boundary phase as well as the density of sintered samples have maximum values with increasing the holding time. Among the range of holding time in this research (0-90min), however, the room temperature strength of GPS silicon nitride ceramics increases with expanding the holding time.
