The fracture toughness of a dense, sintered commercial /alpha/-silicon carbide was determined for temperatures from 20/sup 0/ to 1400/sup 0/C using the straight- and chevron-notched test specimens and also controlled-surface-microflow specimens, all in three-point bending. The flexural strengths were also measured for the same range of temperatures and the trend is compared with that of the toughness. Measurements from this study are discussed and also compared with other results in the literature.
