SG Type SiC Heating element

SG Type SiC Heating element

During the process of heating with electricity, the resistivity of silicon carbide rods exhibits nonlinear changes with different temperatures. At room temperature to 800 ° C (domestic silicon carbide rod), the resistivity rapidly decreases with increasing temperature, reaching its lowest value at 800 ° C. As the temperature further increases, the resistivity begins to increase, and the magnitude of the increase becomes increasingly higher. The maximum operating temperature of silicon carbide rods cannot exceed 1450 ° C. If the operating temperature exceeds this value, silicon carbide rods will rapidly age and their service life will be seriously affected.
