Silicon Carbide Heating Elements with 1650°C Max Service Temp, Corrosion Resistant and Customized Sizes for Industrial Furnaces

Silicon Carbide (SiC) ceramic heating elements represent the pinnacle of non-metallic, high-temperature electric heating technology. Engineered from premium-grade green silicon carbide through advanced pressing, high-temperature siliconizing, and recrystallization processes, these elements outperform traditional metal heaters with superior oxidation resistance, corrosion resistance, and extended service life—making them the ideal heating solution for demanding industrial applications.

• Ultra-High Temperature Performance: Stable operation in environments up to 1650 °C (3000°F)
• Energy-Efficient Design: Patented cold-end manufacturing process ensures optimal heat zone resistance, reducing energy waste and preventing furnace body damage
• Long Service Life: Exceptional resistance to thermal shock, deformation, and chemical corrosion
• Easy Installation & Maintenance: Standardized designs simplify integration and replacement, minimizing downtime
• Versatile Application: Suitable for glass melting, ceramics sintering, powder metallurgy, magnetic materials processing, and mechanical heat treatment

We offer a comprehensive range of SiC heating element configurations to match your specific furnace design:

Standard Sizes Available: Diameters from 10mm to 54mm, including popular imperial sizes: 31.7mm (1.25"), 38.1mm (1.5"), and 44.4mm (1.75").

SiC heating elements exhibit unique resistance characteristics essential for effective thermal management:

• High Specific Resistance: 600-1400 Ω*mm²/m at 1050°C hot zone temperature
• Temperature-Resistance Curve:
  • Negative temperature coefficient (NTC) from room temperature to 800 °C
  • Positive temperature coefficient (PTC) above 800 °C
• Surface Load Optimization: Proper selection based on furnace structure ensures maximum element longevity

• Secure Packaging: Each element is individually wrapped in anti-static material and placed in reinforced cartons
• Global Logistics: We ship worldwide via air, sea, and express courier services
