Summary

Thermomechanical properties of a reaction-formed silicon carbide (NSC-20) material containing –10-12 at% free silicon have been characterized. This material was fabricated by the infiltration of molten silicon into a microporous carbon preform. The average room temperature flexural strength of this material was 370·28 MPa. The flexural strength increased with temperature up to 1100°C in air. There was no loss of strength up to 1371°C, but there was a large variation in strength at high temperatures.
