SiC also has 3x the thermal conductivity, meaning 3x the cooling capability of silicon. Figure 1: Semiconductor Material comparisons (Silicon Carbide vs Silicon vs Gallium Nitride) Silicon carbide, also known as carborundum, is a compound semiconductor made up of silicon and carbon.
The high thermal conductivity enables SiC-based devices to operate at extremely high power levels whilst still being able to dissipate the large amounts of generated excess heat. SiC devices can operate at high frequencies, such as radio and microwave frequency ranges, due to the larger saturated electron drift velocity, which is two to two-and-a-half times larger than that of Si .
The refractories made of silicon carbide exhibit high thermal conductivity that is ten times higher than fireclay refractories. Global crude steel production increased by 4.5% from 2017 to 2018. Thus, increasing steel production is likely to propel the demand for refractories, which in turn is anticipated to augment the growth of the market in near future.
