Notes:
The effect of seeding on the microstructure and mechanical properties of hot-pressed silicon nitride was investigated by introducing large, elongated b-Si3N4 particles into an α-Si3N4 matrix. Densification and fracture toughness were followed in the presence of Y2O3 as sintering aid. The concentration of seeds varied from 0 to 5 wt%. The maximum fracture toughness was 8.0 MPam1/2 for a material with 3 wt% seeds, hot pressed at 1750oC, for 4h
