What is silicon carbide
Silicon carbide (SiC) is a third-generation compound semiconductor material. The cornerstone of the semiconductor industry is chips, and the core materials for making chips are divided into three categories according to the historical process: first-generation semiconductor materials (mostly high-purity silicon currently widely used), second-generation compound semiconductor materials (gallium arsenide, indium phosphide ), third-generation compound semiconductor materials (silicon carbide, gallium nitride).
Silicon carbide will be the most widely used basic material for semiconductor chips in the future due to its superior physical properties: high band gap (corresponding to high breakdown electric field and high power density), high electrical conductivity, and high thermal conductivity.
The functions of silicon carbide are as follows: First, it can effectively reduce friction, help improve the traction of the vehicle and the efficiency of the engine, thereby improving the acceleration and overall performance of the vehicle; second, it can effectively reduce engine noise and improve the wear resistance of metal parts Sex, reduce the consumption of lubricating oil; In addition, silicon carbide also has a certain fire prevention effect, which can reduce the damage to the vehicle when a fire breaks out.
Silicon carbide has an important influence on new energy vehicles. First of all, it can improve the engine efficiency of new energy vehicles and help new energy vehicles achieve higher fuel economy; secondly, it can extend the service life of new energy vehicles and reduce the damage rate of accessories; finally, it also helps New energy vehicles provide a quieter operating environment and reduce noise emissions, thereby improving the driving environment.
