Influences of rare‐earth oxide additives on the formation and properties of porous Si 2 N 2 O ceramic
Here we prepared porous silicon oxynitride (Si 2 N 2 O) ceramics by reaction sintering of SiO 2 and Si 3 N 4 using five different rare‐earth oxides ( RE 2 O 3 , RE = Lu, Yb, Y, Sm, and La) as sintering aids. The influences of RE 2 O 3 on the formation, densification, microstructure, and mechanical...
