Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
Silicon carbide in electric vehicles stands for more efficiency, higher power density and performance. Particularly with an 800 V battery system and a large battery capacity, silicon carbide leads to a higher efficiency in inverters and thus enables longer ranges or lower battery costs.
