Silicon Carbide (SiC) Electric Heating Elements
Silicon Carbide (SiC) heating elements are premium non-metal electric heaters specifically designed for extreme temperatures and harsh industrial environments. Manufactured from high-purity green silicon carbide, they undergo precise forming, siliconizing, and recrystallization processes at high temperatures to deliver reliable, long-lasting performance. These elements represent the optimal economical solution for demanding high-temperature applications.
Key Applications of SiC Heating Elements
- Electronics Manufacturing
- Metallurgical Processing
- Aluminum & Zinc Industries
- Ceramics & Porcelain Kilns
- Float Glass Production
- Optical Glass Manufacturing
- Laboratory & Research Furnaces
- Fluorescent Powder Processing
Operating Guidelines: Surface Load & Atmospheric Effects
For optimal performance and extended lifespan, it is crucial to operate within recommended surface load limits based on your furnace atmosphere and temperature conditions.
| Atmosphere | Max. Furnace Temp. (°C) | Max. Surface Load (W/cm²) | Effect on SiC Element |
|---|---|---|---|
| Ammonia (NH₃) | 1290 | 3.8 | Produces methane, damaging the protective SiO₂ layer |
| Carbon Dioxide (CO₂) | 1450 | 3.1 | Corrosive to silicon carbide |
| Carbon Monoxide (CO) | 1370 | 3.8 | Carbon deposition can impair the SiO₂ layer |
| Halogen Gases | 704 | 3.8 | Highly corrosive; destroys SiO₂ layer |
| Hydrogen (H₂) | 1290 | 3.1 | Produces methane, damaging the protective SiO₂ layer |
| Nitrogen (N₂) | 1370 | 3.1 | Can form an insulating silicon nitride layer |
| Sodium Vapor | 1310 | 3.8 | Corrosive to silicon carbide |
| Silicon Dioxide | 1310 | 3.8 | Corrosive to silicon carbide |
| Oxygen / Air | 1310 | 3.8 | Oxidizes SiC (forms protective SiO₂ at correct temps) |
| Water Vapor | 1090-1370 | 3.1-3.6 | Forms silicon hydrates, accelerating aging |
| Hydrocarbons | 1370 | 3.1 | Carbon pickup leads to "hot spot" failure |
