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 |
