PRESSURELESS SINTERING OF WHISKER REINFORCED ALUMINA COMPOSITES

摘要

A composite and pressureless sintering procoss for making whisker-reinforcedalumina composite using about 2 wt% to about 7.5 wt% of a nitride modifier consistingessentially of silicon nitride, aluminum nitride, or mixture thereof produces a sinteredbody having a density of greaer than about 95% theoretical.
