Summary

Alumina is a well known sintering additive for Si3N4-Y2O3 system. A series of Si3N4-6 wt % Y2O3 compositions containing torn 0 to 4 wt % Al2O3 were injection molded and sintered. The room-temperature and high-temperature (to 1400°C) strength and oxidation resistance were measured to establish the applicability range of these compositions with respect to high temperature structural applications.
