Electronic Applications of silicon carbide including mild-emitting diodes (LEDs) and detectors in early radios had been initial demonstrated around 1907. SiC is Employed in semiconductor electronics devices that function at high temperatures or high voltages, or each. Therefore, the hotter a semiconductor like silicon is, the higher its electrical conductivity. https://www.quora.com/profile/Trevor-Flatcher-2/Advantages-of-Silicon-Carbide-Materials-in-High-Temperature-Electronic-Devices-Silicon-carbide-SiC-has-emerged-as-a-c
