How is Silicon Carbide Useful?

Historically, manufacturers use silicon carbide in high-temperature settings for devices such as bearings, heating machinery components, car brakes, and even knife sharpening tools. In electronics and semiconductor applications, SiC’s advantage main advantages are:silicon carbide manufacturers

– High thermal conductivity of 120-270 W/mK

– Low coefficient of thermal expansion of 4.0×10^-6/°C

– High maximum current density

These three characteristics combined give SiC excellent electrical conductivity, especially when compared to silicon, SiC’s more popular cousin. SiC’s material characteristics make it highly advantageous for high power applications where high current, high temperatures, and high thermal conductivity are required.

In recent years, SiC has become a key player in the semiconductor industry, powering MOSFETs, Schottky diodes, and power modules for use in high-power, high-efficiency applications. While more expensive than silicon MOSFETs, which are typically limited to breakdown voltages at 900V, SiC allows for voltage thresholds at nearly 10kV.

SiC also has very low switching losses and can support high operating frequencies, which allows it to achieve currently unbeatable efficiencies, especially in applications that operate at over 600 volts. black silicon carbide powderWith proper implementation, SiC devices can reduce converter and inverter system losses by nearly 50%, size by 300%, and overall system cost by 20%. This reduction in overall system size lends SiC the ability to be extremely useful in weight and space-sensitive applications.
