Abstract

Silicon nitride ceramic was produced by coating the silicon nitride powder with alumina, drying the powder, hot-pressing and sintering. The ceramic demonstrated fracture toughness and wear resistance much higher than commercially available silicon nitride. Improvement of mechanical properties resulted from formation of crystalline sialon in grain boundaries.
