U Shape Silicon Carbide Heating Element for Industrial Kilns and Furnaces
U Shape Silicon Carbide Heating Element
Description
Silicon Carbide Heating Elements is a kind of non-metal high temperature electric heating element. Silicon Carbide Heating Elements is made of selected high quality green silicon carbide as main material, which is made into blank, siliconization under high temperature and recrystallized. In oxidizing atmosphere, its service temperature can reach 1450ºC and continuous use life can reach 2000 hours.
Silicon Carbide Heating Elements Applications
SiC heating elements can be used in the furnace temperature 600C-1400C, directly in the air use as well, and it need not any protective atmosphere. Because of SiC heating elements well performance, they are widely used in high temperature furnace, ceramics, glass, analysis and test, semiconductor, science research.. etc
Recommended surface load and Influences to Surfaces of the Elements in Different Operating Temperature
| atmosphere | Furnace Temperature(°C) | Surface Load(W/cm2) | The influence on the Rod |
| Ammonia | 1290 | 3.8 | The action on SiC produces methane and destroys the protection film of SiO2 |
| Carbon dioxide | 1450 | 3.1 | Corrode SiC |
| Carbon monoxide | 1370 | 3.8 | Absorb carbon powder and influence the protection film of SiO2 |
| Halogen | 704 | 3.8 | Corrode SiC and destroy the protection film of SiO2 |
| Hydrogen | 1290 | 3.1 | The action on SiC produces methane and destroys the protection film of SiO2 |
| Nitrogen | 1370 | 3.1 | The action on SiC produces insulating layer of silicon nitride |
| Sodium | 1310 | 3.8 | Corrode SiC |
| silicon dioxide | 1310 | 3.8 | Corrode SiC |
| Oxygen | 1310 | 3.8 | SiC oxidized |
| Water-vapor | 1090-1370 | 3.1-3.6 | The action on SiC produces hydrate of silicon |
| Hydrocarbon | 1370 | 3.1 | Absorb carbon powder resulted in Hot pollution |
