- structural integrity;
- fracture stress
Silicon nitride with and without additives has been produced by hot isostatic pressing under different conditions. The HIP cycle parameters and grade of powder used have been found to affect the density, the hardness and the fracture toughness of the material produced. Sintering aids, on the other hand, have been found to affect the fracture toughness only. Materials HIPed with additives displayed a higher fracture toughness than materials HIPed without additives.
