BaSiCs of SiC Series: Silicon Carbide’s Unique Properties and Applications
Although it might seem like a recent innovation, silicon carbide (SiC) has actually been in use since the late 1800s, beginning as an abrasive material and later finding applications in a wide variety of industries (including semiconductors). The wide-ranging use of SiC is a natural consequence of the material’s extraordinary physical traits.
