While silicon carbide has many advantageous properties, its high cost of production compared to alternatives such as silicon often limits its applications. Additionally, while it is generally regarded as safe, silicon carbide dust can be harmful if inhaled, and adequate safety measures must be taken during its production and handling. Conclusion
This is happening because silicon-based power semiconductors, though still being optimized, are reaching their operational limit in terms of conduction and switching losses. Silicon carbide's wider bandgap (3.26eV vs. 1.12eV for silicon) reduces such losses and delivers superior high-temperature and high-frequency performance.

SiC is the only compound of group IV elements comprised of Silicon (Si) and Carbon (C). Fig. 2 shows the temperature dependence of the intrinsic carrier density for SiC and Si [4].Due to the wide bandgap, SiC has an extremely low intrinsic carrier density (5 × 10 − 9 cm − 3 at room temperature) whereas the density is about 1 × 10 10 cm − 3 in Si, …
This mixture is then subjected to high temperatures in an electric resistance furnace. Under these conditions, a chemical reaction occurs where the carbon and silica combine to form silicon carbide and carbon monoxide. Once formed, the silicon carbide is crushed and screened into specific sizes to produce grit for abrasive purposes.
Furthermore, these properties of silicon carbide allow it to be competitive with boron carbide but at a considerably lower manufacturing cost [99–101].
