Description
Silicon Carbide (SiC) Heating Elements | High-Temp Heating to 1600°C
High-performance silicon carbide heating elements for temperatures up to 1600°C. Superior thermal shock resistance & power density. Explore SW, U-Type, W-Type models for industrial furnaces.
Product Overview
Our Silicon Carbide (SiC) Heating Elements are engineered for extreme industrial heating applications. Capable of operating at temperatures up to 1600°C (2912°F), they deliver unmatched heat output, rapid thermal response, and long service life in both air and controlled atmospheres, making them a superior replacement for traditional metal alloy heaters.
Key Advantages of SiC Heating Elements
  • Exceptional Power Density: Generate 5 to 10 times more heat per unit surface area than standard Nichrome wire, enabling faster heat-up and higher operating temperatures.
  • Superior Mechanical Strength: Excellent resistance to thermal shock and physical deformation, ensuring reliability under rapid temperature cycling and demanding industrial conditions.
  • Clean & Quiet Operation: The heat source is entirely free of noise, emissions, and air pollution, making it ideal for sensitive processes like sintering, brazing, and crystal growth.
Product Types & Applications
1. SW Type (Standard Rod)
  • Applications: Universal heating element for a wide range of furnace types.
  • Features: Operating range from 600°C to 1400°C (up to 1600°C in suitable conditions). Can be installed both vertically and horizontally.
  • Ideal For: General high-temperature furnaces, research labs, and ceramic kilns.
2. U-Type (Hairpin Shape)
  • Applications: Compact furnaces where space is constrained.
  • Features: Consists of two identical SiC rods connected by a low-resistance SiC bridge, which can also serve as a mounting point. Provides a concentrated heat zone.
  • Ideal For: Tube furnaces, and processes requiring a localized high-temperature zone.
3. W-Type (3-Phase Configuration)
  • Applications: Large-scale industrial heating requiring high power input.
  • Features: A three-rod, one-side terminal design (SGC for vertical, SGD for horizontal installation) that connects directly to a three-phase power supply.
  • Ideal For: Float glass production, large batch sintering, and other heavy-duty industrial processes.

Operating Guidelines & Atmosphere Compatibility
The performance and lifespan of SiC elements are highly dependent on furnace temperature and atmosphere.
Atmosphere Max Recommended Temp (°C) Surface Load (W/cm²) Potential Risk & Effect
Air / Oxygen 1600 15-25 Slow oxidation forms protective SiO₂ layer.
Hydrogen (H₂) 1290 10-15 Can produce methane, destroying the protective SiO₂ layer.
Nitrogen (N₂) 1370 10-15 Can form an insulating silicon nitride layer, increasing resistance.
Water Vapor 1090-1370 10-15 Reacts to form silicon hydrate, accelerating element degradation.
Chlorine / Halogen 704 15-25 Highly corrosive, rapidly destroys the SiO₂ layer and attacks SiC.
Critical Installation & Usage Notice
  • Storage: Keep elements dry and protected from moisture to prevent performance degradation.
  • Matching: For multi-element furnaces, sort and group elements so their resistance values are within a 10% tolerance to ensure even load distribution.
  • Handling: SiC is hard but brittle. Handle with care during installation and maintenance to avoid breakage.
  • Start-Up: Always use a controlled ramp-up voltage when starting a cold furnace. Avoid immediate full power to prevent excessive inrush current from damaging the elements.
  • Replacement: Replace damaged elements with new ones of similar resistance. If multiple elements have failed or their resistance has increased significantly, consider a full set replacement for balanced performance.
