Thermal Expansion of Silicon Carbide Monofilaments and

The coefficient of thermal expansion (CTE) of a 140‐μm‐diameter SiC monofilament was determined to be 6.5 ± 0.5 × 10 −60 C −1 in the temperature range 25°–900°C. Heat treatment of the fibers at 1400°C for 90 min resulted in both an increase in the intensities of the SiC s and a reduction of their width, indiing some grain growth.
