Summary

Statistically-designed experiments were used to study the significant effects of composition and professing variables on the density and strength of sintered SiC. The best results were obtained by an attritor mixing process which yielded strengths in excess of 80 Ksi (550 MPa). Strengths measured at 1200°C and 1400°C were the same as those at room temperature. Annealing in air significantly improved strength. Molding yields were improved and flaw distributions were found to follow a Poisson distribution. Hip'ing and proof testing will be discussed.
