be degraded, the sintering additives can be used to effectively improve the densification and tailor the structure and mechanical properties of silicon nitride (Si3N4) ceramics [14-18]. LIU et al [9] successfully fabricated the stereolithographical dense Si3N4 ceramics (ρ=3.28 g/cm3) using 5 wt% Y2O3 and 3 wt% Al2O3 as the sintering additives. In contrast, activated sintering techniques, including gas......
