Description:

MoSi₂ heating elements (molybdenum disilicide heaters) offer exceptional performance in high-temperature industrial processes. With a density of 5.5 g/cm³, these disilicide-molybdenum heaters are ideal for sintering ferrites, technical ceramics, refractories, and glass manufacturing applications. They operate reliably in continuous or periodic cycles within neutral, vacuum, or oxidizing atmospheres at temperatures up to 1800°C.

A key advantage of MoSi₂ heaters is the self-forming protective silicon dioxide (SiO₂) layer that prevents further oxidation, ensuring long service life and thermal stability.

Physical Properties of MoSi₂ Heating Elements

Chemical Properties & Operating Guidelines

MoSi₂ heating elements are designed for high-temperature use in oxidizing environments. The protective SiO₂ layer prevents melting and degradation. However, prolonged use between 400°C and 700°C must be avoided, as this temperature range promotes accelerated oxidation and potential damage.

Key Advantages of MoSi₂ Heaters

• Self-Protecting Oxidation Resistance: SiO₂ film ensures longevity.

• Positive Temperature Coefficient: Resistance increases with temperature, enabling faster heating.

• Stable Electrical Resistance: Simplifies replacement and system integration.

• High Power Density: Efficient heating in compact furnace designs.

Main Applications

• Sintering of ferrites

• Technical ceramics & refractory materials

• Glass melting and processing

• Single crystal growth

• High-temperature research & laboratory furnaces
