ABSTRACT:
A composite and pressureless sintering process for making whisker-reinforced alumina composites using about 2 to about 7.5 wt. % of a nitride modifier consisting essentially of silicon nitride, aluminum nitride, or mixtures thereof produces a sintered body having a density of greater than about 95% theoretical.
