Notes:
Effect of iteration times on mechanically-activated combustion synthesis of high α-contentSi3N4 powders was investigated. Properties of the as-synthesized powders such as α-content (Cα) as wellas specific surface area (As) were examined. Results showed that both of Cα and As became higher afteriteration reactions. The mechanical properties of the sintered bulk ceramics from as-synthesized powderswere also tested to reveal the sinterability of the powders. Results showed that relative density of all thesintered bulk ceramics were higher than 97%. Furthermore, fracture toughness had a trend of becominghigher, which reached a value of 10.2 MPam0.5. Correspondingly, bending strenth became a bit lower
