Silicon Carbide (SiC)

Silicon carbide (SiC) is a ceramic compound combining silicon and carbon in a 1:1 ratio, engineered as a wide-bandgap semiconductor with exceptional hardness and thermal stability. It is widely deployed in high-temperature power electronics (MOSFETs and Schottky diodes), abrasive applications, refractories for furnace linings, and emerging automotive/renewable energy inverters where its superior thermal conductivity and thermal shock resistance outperform traditional silicon. Engineers select SiC over conventional semiconductors when operating environments exceed 200°C or when high switching frequencies and power density are critical, though cost and manufacturing maturity remain considerations relative to established Si technology.
