-3-17 · 1-5. Thermal Expansion Coefficient: Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. When a substance is heated, its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in ...

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 peaks and a reduction of their width, indiing some grain growth.
