MoSi2 Heating Element
At Furn-Tek, our focus is high-performance industrial heating — and that includes more than just silicon carbide. We also offer MoSi₂ (Molybdenum Disilicide) elements for extreme-temperature applications reaching up to 1800 °C in oxidizing atmospheres.
Product Specification
Maximum operating temperature:
1700–1800 °C
Atmosphere:
Best suited for oxidizing or neutral environments
Resistance profile:
- Positive Temperature Coefficient (PTC) — resistance increases with temperature
- Long service life in high-purity processes (glass, lab furnaces, etc.)
- Self-forming protective silica layer resists oxidation
- High power density — often 5–10 W/cm² and higher
Common types:
- U Shape (M1700U, M1800U)
- W Shape (M1700W)
- Straight or L-Shape (custom lengths)
Ideal for:
- High-temperature lab furnaces
- Glass melting and processing
- High-purity ceramics and sintering
- Heat treatment under oxidizing conditions
Custom-Built MoSi₂ Elements
Just like our GLO-BARs, MoSi₂ elements can be manufactured to your exact specifications, including:
- Diameter (typ. 3/6, 4/9, 6/12, 9/18 mm cold/hot ends)
- Heated zone length and terminal leg length
- Resistance values matched to system voltage
- Mechanical configurations (U, W, L, custom)
