Abstract
Densification of a‐Sic powders with no premixed sintering aids (type 1) and with premixed B and C (type 2) was investigated by sintering them at 2150° to 2200°C for 30 min. Flexure strengths, Weibull moduli, and fracture flaws were characterized for type 2 α‐SiC only. The results were compared with those for a state‐of‐the‐art sintered a‐Sic material.
