The objective of this work was to investigate the effect of two different sintering additives (CeO 2 and Y 2 O 3 - Al 2 O 3 ), sintering time and amount of β-Si 3 N 4 seeds on the densification, mechanical properties and microstructure of self-reinforced Si 3 N 4 based composites obtained by pressureless sintering. Preparation of β-St 3 N 4 seeds, also obtained by a pressureless sintering procedure, is described. Samples without seeds were prepared for comparison. The results imply that self-reinforced silicon nitride based composites with densities close to the theoretical values and with fracture toughness of 9.3 MPa m 1 / 2 can be obtained using a presureless sintering procedure.
