N2 - To enhance the sinter ability of Si3N4, powders mixed with 0, 2, and 5 wt% Y2O3 were explosively shock‐treated. Compacts of these powders were encapsulated in 96% silica glass containers and isostatically hot‐pressed. The shocked Si3N4 with 5 wt% Y2O3 was pressed to a density of 3.09 g/cm3 (95.4% of theoretical) at 1400°C under 430 MPa for 3 h, whereas the unshocked material attained only 82.4% of theoretical density under the same hot isostatic pressing conditions.
