The Coefficient of Thermal Expansion (CTE) of Silicon Carbide

Silicon carbide (SiC) is an extremely hard ceramic material widely utilized as an abrasive and for the production of high-performance power electronics components. Furthermore, SiC’s resistance to extreme temperatures makes it suitable for industrial settings. However, when SiC is used in electronic devices with other materials it may experience mechanical stress due to CTE mismatch between its CTE and that of the bonding material. Matching their CTEs may help alleviate such tension. Coefficient of Thermal Expansion (CTE) Coefficient of Thermal Expansion (CTE) is an important parameter that measures how a material expands or contracts when exposed to temperature changes, playing an essential role in both designing and building solid artifacts …
