Brief description of silicon carbide heating element:
Silicon carbide rod (SiC) electric heating element is a rod-shaped non-metallic high-temperature electric heating element made of green high-purity hexagonal silicon carbide as the main raw material, processed into embryo, silicified at high temperature and recrystallized at 2200 ℃. The surface temperature of the rod can reach 1550 ℃.
Advantages of silicon carbide electric heating element:
1. The silicon carbide rod is hard and brittle, has a small expansion coefficient, good cold and heat resistance, and is not easy to deform,
2. Good chemical stability, strong acid resistance, no reaction with strong acid.
3. Strong heat dissipation and accurate temperature control
4. The use method is simple and can be used for parallel, series and hybrid connections,
5. Fast temperature rise, strong thermal oxidation resistance
