Silicon Carbide (SiC) Heating Elements
Silicon Carbide (SiC) Heating Elements are premium non-metallic electric heating components engineered for extreme-temperature industrial applications. Manufactured from high-quality green SiC powder, these elements undergo high-temperature siliconization and recrystallization processes. With exceptional temperature resistance up to 1625°C, they are ideal for ceramic firing, metallurgy, glass production, and laboratory furnaces.
Key Features & Advantages
- Extreme temperature resistance (up to 1625°C)
- Excellent oxidation and corrosion resistance
- Rapid heating capability
- Low thermal expansion coefficient
- High mechanical strength and durability
