Effects of Impurity Oxygen Content in Raw Si Powder on Thermal and Mechanical Properties of Sintered Reaction-Bonded Silicon Nitrides

Sintered reaction‐bonded silicon nitrides (SRBSNs) were fabricated from commercially available low‐grade Si powder containing 1.6 mass% of impurity oxygen and 500 ppm of metallic impurities. Powder compacts of the raw Si powder doped with Y2O3 and MgO/MgSiN2 as sintering additives were nitrided at 1...
