Super MoSi₂ Heating Elements
Premium high-temperature performance for industrial applications worldwide
Our high-performance Molybdenum Disilicide (MoSi₂) heating elements are engineered to excel in extreme high-temperature settings across the globe. Ideal for use in ceramics, magnets, glass, metallurgy, and refractory material industries, these elements offer superior durability, energy efficiency, and long-term reliability.
Key Features & Advantages
Exceptional High-Temp Performance
Reliable operation from 500°C up to 1700°C, with a maximum withstand temperature of 1800°C.
Self-Forming Protective Layer
In oxidizing atmospheres, a quartz glass layer forms automatically, preventing oxidation and extending service life.
Stable Electrical Resistance
Predictable resistivity increase with temperature and consistent performance over time—allowing easy combination of old and new elements.
Robust Mechanical Properties
- Volume Density: 5.5-5.6 g/cm³
- Bend Strength: 15-25 kg/cm²
- Vickers Hardness: 570 kg/mm²
Easy Installation & Minimal Maintenance
Simplified integration and dependable operation reduce downtime and total cost of ownership.
Avoid prolonged use between 400-700°C to prevent low-temperature oxidation.
